Ethical Leadership, Managerial Judgment and Executive Effectiveness: What Separates a Good Executive from a Merely Confident One

Lessons 26 to 29 built a working vocabulary for leadership: classical and contemporary theories of what leadership is (Lesson 26), the transformational, transactional and servant styles leaders actually adopt (Lesson 27), the emotional-intelligence skills that shape how a leader reads a situation before deciding (Lesson 28), and the communication, delegation, coaching and feedback behaviors through which any of that gets enacted day to day (Lesson 29). None of those four lessons asks whether a leader's conduct meets an ethical standard, whether a specific decision reflects sound reasoning, or whether the leader's organization is actually better off as a result. Those are the three questions this lesson owns, and keeping them separate matters because popular management writing routinely collapses them into one impression: a leader who sounds confident and decisive is assumed to be ethical, judicious and effective all at once, when each of the three is measured differently, predicted by different things, and can move independently of the other two.

Before ethical leadership had a settled definition, it was usually folded into related ideas, transformational leadership's concern for followers' development, or authentic leadership's emphasis on self-awareness, without a boundary of its own. Michael Brown, Linda Trevino and David Harrison's (2005) article in Organizational Behavior and Human Decision Processes gave the construct a specific, citable definition: ethical leadership is "the demonstration of normatively appropriate conduct through personal actions and interpersonal relationships, and the promotion of such conduct to followers through two-way communication, reinforcement, and decision-making." The definition has two separable halves. The first half, personal conduct, is what Brown and Trevino's (2006) follow-up review in The Leadership Quarterly calls being a moral person: honest, trustworthy, principled behavior in the leader's own actions. The second half, promoting that conduct in others through communication and reinforcement, is being a moral manager: setting ethical standards, modelling them visibly, rewarding ethical conduct and disciplining unethical conduct so the standard is not just personal but transmitted.

The ELS asks followers to rate statements such as whether their leader disciplines employees who violate ethical standards, listens to what employees have to say, and makes fair and balanced decisions. Brown, Trevino and Harrison (2005) reported that scores on the scale predicted outcomes including follower satisfaction, perceived leader effectiveness and willingness to report problems to management, net of other known predictors such as transformational leadership and interactional fairness. That last point matters: the construct was built, and tested, specifically to show it adds something beyond leadership styles already in the literature, not simply to relabel them.

A follower-reported scale has a structural limitation worth stating plainly rather than glossing over. Most studies using the ELS are cross-sectional: the same survey asks the same respondent to rate the leader's ethics and the respondent's own satisfaction or commitment at the same point in time. A significant correlation between the two is consistent with ethical leadership causing better follower attitudes, but it is equally consistent with the reverse, a follower who is already satisfied for unrelated reasons rating the same supervisor more favorably on every item, including the ethics items, a pattern researchers call common-method bias. Longitudinal and multi-source designs exist and reduce this problem, but a manager reading a single study, or a training slide summarizing "ethical leadership improves performance," should not read a correlation as proof that the leadership caused the outcome. The construct is real and the measurement is a genuine advance over an undefined, intuitive notion of ethical leadership; the causal claim built on top of it needs its own evidence, study by study, which is a distinction this lesson will return to when it reaches Drucker's prescriptions, built on a very different kind of evidence altogether.

Herbert Simon's Administrative Behavior (1947) supplied the concept that most later research on managerial decision-making, including the two biases discussed next, assumes rather than restates. Classical economic models of decision-making assumed a decision-maker who could identify every alternative, calculate every consequence and choose the option that maximizes value, a standard Simon called optimizing. Simon argued that real administrators cannot do this, not because they are careless but because the task itself exceeds what any human mind, however capable, can process: information is incomplete, time is limited, and the number of alternatives in a genuinely complex decision is too large to search exhaustively. He coined bounded rationality to describe decision-making constrained by these real limits, and satisficing, choosing the first option that clears an acceptable threshold rather than continuing to search for the best one, as the practical strategy bounded rationality actually produces. This is not a criticism of managers; it is a description of the task. Once bounded rationality is taken seriously, it stops being surprising that experienced, intelligent executives make systematic, predictable errors under pressure. The two best documented are escalation of commitment and overconfidence, and both are errors bounded rationality predicts rather than anomalies that contradict it.

Barry Staw's (1976) study, published in Organizational Behavior and Human Performance under the title "Knee-Deep in the Big Muddy," a reference to a Pete Seeger song about continuing to wade into a river despite rising danger, gave the field its founding term for a specific failure pattern: escalation of commitment, the tendency to increase investment in a failing course of action, particularly when the decision-maker feels personally responsible for the original choice. Staw had participants play the role of a corporate financial officer allocating funds to one of two company divisions, then gave them feedback that the chosen division was performing poorly, and measured how much additional money they allocated to it afterward. Participants who had personally made the original investment decision committed more additional funds to the failing division after negative feedback than participants who had merely inherited someone else's earlier decision, even though both groups saw identical performance information. The result pointed to self-justification rather than miscalculation: continuing to fund a visibly failing choice let the original decision-maker avoid admitting the first decision had been wrong, a psychological cost separate from the financial one.

Hal Arkes and Catherine Blumer's (1985) article, "The Psychology of Sunk Cost," published in the same journal under its later name, Organizational Behavior and Human Decision Processes, pushed the explanation further with a separate set of experiments and did not require personal responsibility for the original decision to find the effect. In one study, people chose a less enjoyable ski trip over a more enjoyable one simply because more money had already been spent on it and could not be recovered either way, a choice standard economic reasoning treats as irrational, since a cost already paid should not affect which future option delivers more value. Arkes and Blumer proposed that part of the pull toward sunk-cost-driven choices is a learned aversion to appearing wasteful, a norm absorbed well before anyone becomes a manager, that attaches itself to decisions where it has no logical place. The practical implication for executives is specific rather than general: the trigger is not simply "a project is struggling," which happens constantly and rarely demands escalation. It is the combination of a large prior investment, a decision-maker who feels personally identified with the original choice, and a framing in which stopping looks like admitting waste rather than like a normal, correctable update given new information.

Escalation of commitment explains why a bad decision, once made, is hard to reverse. Overconfidence helps explain why executives make decisions whose risk they have already underestimated before the first dollar is spent. Ulrike Malmendier and Geoffrey Tate's (2005) study in The Journal of Finance measured overconfidence in actual chief executives rather than in a laboratory sample, using a behavioral indicator: CEOs who repeatedly held vested, in-the-money stock options well past the point a diversified investor would normally exercise them, effectively keeping personal wealth concentrated in their own company's stock, were classified as overconfident. Malmendier and Tate found that CEOs meeting this behavioral definition of overconfidence were more likely to make value-destroying acquisitions and overinvested more sharply when internal cash was available, consistent with a specific mechanism: an overconfident CEO overestimates the returns their own projects will generate and treats external financing, debt or equity that would expose the decision to outside scrutiny, as needlessly costly compared with spending internally generated cash the firm already controls. The bias is not a lack of intelligence or experience; the CEOs in the sample had generally succeeded enough to reach the role. It is a specific, measurable distortion in how confidently they judge their own projects' prospects relative to projects proposed by others.

Overconfidence and escalation of commitment reinforce each other in a way that matters for the ethical dimension of executive judgment. An executive who already overestimates a project's likely success is less likely to interpret early negative signals as evidence the project should stop, and more likely to interpret the same signals as a temporary setback a confident leader should push through. Once money has already been committed under that confidence, the self-justification Staw documented adds a second reason to keep going. The combination means that by the time a genuinely difficult disclosure decision arrives, whether to tell a board, a regulator or an investor the truth about a struggling initiative, the executive facing it has often spent months in a reasoning pattern that made an honest admission progressively harder to reach, not because they are dishonest by disposition but because overconfidence and sunk-cost reasoning had already narrowed what felt like the available options.

Peter Drucker's "What Makes an Effective Executive," published in Harvard Business Review in June 2004 and later reissued as a standalone Harvard Business Review Classics volume, opens with a deliberately provocative claim: effective executives, in Drucker's observation, varied enormously in personality, strengths, values and style, which is precisely why he argued that effectiveness cannot be a personality trait, charisma included. What they shared, in his account, was a set of eight practices: asking "what needs to be done," asking "what is right for the enterprise," developing action plans, taking responsibility for decisions, taking responsibility for communicating, focusing on opportunities rather than problems, running productive meetings, and thinking and saying "we" rather than "I." Several of these connect directly to the material already covered in this lesson. Taking responsibility for a decision, in Drucker's formulation, includes periodically revisiting it and being willing to reverse it, which is a direct, if informally stated, answer to escalation of commitment: a decision owner who has pre-committed to checking the decision again is less likely to let sunk cost quietly take over the review.

The claim deserves to be taken seriously and also read critically, and the two are not in tension. Drucker's eight practices come from roughly sixty-five years of consulting observation across many organizations, which is a genuinely substantial base of experience, but it is not a sampled study with a defined population, a measurement instrument, a reported effect size, or any mechanism by which the claim could be shown false. Phil Rosenzweig's (2007) book The Halo Effect examined this exact genre of confident business prescription, built from retrospective accounts of organizations already known to have succeeded or failed, and argued that such accounts are vulnerable to a specific distortion: once a company's financial results are known, observers tend to redescribe its leadership, culture and strategy in matching terms, calling the same decisive style "visionary" when results are good and "reckless" when they are not, which produces an illusion of a clear, causal leadership recipe that the underlying evidence does not actually establish. Rosenzweig's critique was aimed at best-selling business books more broadly, not at Drucker specifically, and Drucker's own claims are narrower and less dependent on after-the-fact company selection than the books Rosenzweig examined. The honest position is that Drucker's eight practices are a serious, experience-based argument worth taking as a hypothesis about effective executive behavior, not a finding with the same evidentiary standing as a peer-reviewed, measured construct like ethical leadership. Rule 12 of this series' standard asks for that distinction to be named rather than smoothed over, and this is the point in the lesson where it has to be.

D. Scott DeRue, Jennifer Nahrgang, Ned Wellman and Stephen Humphrey's (2011) meta-analysis in Personnel Psychology gives the empirical side of this comparison a specific number instead of a general impression. Pooling results across many prior studies, they tested an integrative model in which leader traits, including intelligence, personality and gender, and leader behaviors, including transformational and transactional style and the classic initiating-structure and consideration dimensions, jointly predicted four separate effectiveness criteria: overall leader effectiveness ratings, group performance, follower job satisfaction, and satisfaction with the leader specifically. Combined, traits and behaviors explained a minimum of 31 percent of the variance across these criteria, with leader behaviors generally explaining more of that variance than traits alone, and their preferred model treated behaviors as the pathway through which traits translate into effectiveness, rather than traits acting directly. A figure near 31 percent is a genuinely useful, above-chance predictive result; it is also, read honestly, an admission that the majority of variance in how effective a leader turns out to be is explained by something the model does not capture, situational factors, the specific team, timing and plain chance among them.

Robert Kaiser, Robert Hogan and S. Bartholomew Craig's (2008) article in American Psychologist, "Leadership and the Fate of Organizations," pushed the same question from a different angle, arguing that leadership research and practice had drifted toward judging leaders by reputation, likeability and self-reported competencies rather than by the actual, measurable performance of the team or organization the leader is responsible for. Their proposed corrective was definitional: evaluate leadership by organizational or unit outcomes the leader can plausibly be held accountable for, not by how favorably followers describe the leader's style. Read together with DeRue and colleagues' finding, the empirical picture is consistent and honest about its own limits: specific, codable behaviors predict a meaningful but partial share of effectiveness, outcomes are the right criterion to judge leadership against, and no combination of trait or behavior measures yet accounts for most of what makes one executive more effective than another in a given organization at a given time.

Neither column in that table is simply better than the other across every use. A manager who wants a usable, memorable discipline for Monday morning is often better served by Drucker's eight practices than by a regression coefficient from a meta-analysis. A researcher, a board member evaluating a leadership-development vendor's claims, or a writer in this series deciding how confidently to state a finding needs the second column's standard, because confident prescription and demonstrated finding are not the same achievement, and treating them as equivalent is exactly the kind of unearned certainty Rule 12 and Rule 40 of this series' writing standard ask to be avoided. The honest summary is that Drucker's practices are a serious, experience-grounded hypothesis that happens to overlap, in places, with what the measured research has since found (his point about revisiting decisions anticipates the escalation-of-commitment literature by decades), and that overlap is worth noting without converting an unmeasured claim into a verified one just because parts of it later received independent support.

Lesson 26 catalogued how leadership has been theorized, from trait and behavioral approaches through contingency models. Lesson 27 narrowed to the styles a leader actually adopts in practice, transformational, transactional and servant, each with its own evidence base and its own limits. Lesson 28 argued that emotional intelligence supplies part of the perceptual and self-regulatory skill a leader needs before a good decision is even possible, reading a room, managing one's own reaction to bad news, recognizing a subordinate's genuine distress rather than dismissing it. Lesson 29 described the mechanics, communication, delegation, coaching and feedback, through which whatever style and judgment a leader has gets translated into what followers actually experience day to day. This lesson supplies the piece none of the four own: a specific, measured definition of ethical conduct in leadership, two well-documented failure modes in managerial judgment, and an honest comparison between confident prescriptive advice and the more modest, more quantified empirical record on what actually predicts executive effectiveness.

Put together, the five lessons leave a tension this module does not resolve, and stating it plainly is more useful than pretending it has been settled. The constructs this module has introduced, ethical leadership, emotional intelligence, transformational style, DeRue and colleagues' trait-and-behavior effectiveness model, are only modestly correlated with each other in the research literature, and an executive can score well on one while being unremarkable or worse on another. The chief executive in the Chaitali Apparel Group scenario who chooses option C is behaving as a careful moral manager and as someone resisting escalation of commitment and overconfidence in that specific decision; nothing in that one choice establishes that she is, in Kaiser, Hogan and Craig's (2008) preferred sense, an effective leader of that organization over the next three years, which depends on outcomes this lesson's scenario does not and cannot show. The reverse is equally true: an executive who delivers strong, measurable organizational outcomes by Kaiser and colleagues' standard is not thereby shown to be ethical by Brown and Trevino's standard, and a leadership-development program that teaches Drucker's eight practices is teaching a serious, defensible discipline without being able to claim, on the evidence available, that it reliably produces either ethical conduct or superior organizational performance. Treating "good leadership" as one trait that ethics, judgment and effectiveness all point back to is the simplification this closing lesson has tried to take apart. Later modules, particularly those on performance management and on organizational governance, return to pieces of this same problem from the measurement side; it is left open here because the evidence currently available does not support closing it.

Select a real executive decision you can examine in reasonable depth, a documented corporate crisis, a product recall, a financial restatement, a reported acquisition that later failed, or a decision you observed directly in your own organization, disguised if needed to protect those involved. The decision should have involved some combination of significant prior investment, time pressure, and a choice about what to disclose to a board, regulator, investor or the public.

Prepare a report of 2,000 to 2,500 words that:

1. applies Brown and Trevino's moral-person and moral-manager framework to the executive's conduct, with specific evidence for each half rather than an overall impression;
2. identifies whether escalation of commitment, overconfidence, or both were plausibly present, using Staw's and Arkes and Blumer's criteria and Malmendier and Tate's behavioral logic, and states clearly where the evidence is inferred rather than directly observed;
3. evaluates the decision against at least three of Drucker's eight practices, stating explicitly that this is an application of prescriptive argument rather than a validated empirical test;
4. assesses, using DeRue and colleagues' (2011) or Kaiser, Hogan and Craig's (2008) outcome-based standard, whether the executive should be judged effective based on what actually happened to the organization, independent of how ethical or well-reasoned any single decision appeared; and
5. states explicitly whether your analysis found the three dimensions, ethics, judgment quality and effectiveness, pointing in the same direction or in different directions for this case, and discusses what that implies for how the case should actually be taught or cited.

Use at least five academic or documented sources, including at least three from this article's reference list. State explicitly where information is unavailable and how that gap limits your conclusions, rather than filling the gap with assumption.
