Silent C-Suite Attrition: Predictive Executive Flight Risk
Jun 26, 2025
Empirical Field of the Problem
In 2024, U.S. publicly traded companies turned to the external talent market: 44 % of newly appointed CEOs in the S&P 1500 came from outside the organization—the highest share recorded since 2000. At the same time, the average tenure of departing CEOs slipped to 7.4 years (from about eight years a year earlier) and fell further to 6.8 years in Q1 2025, reflecting boards’ growing impatience with performance dips and rising activist pressure.
Finance is experiencing comparable turbulence. In 2024, global CFO turnover reached 15.1 %, and among S&P 500 companies it remained at a historically high 17.8 %; the average “life span” of a CFO contracted to 5.8 years. The people function is even more volatile: Russell Reynolds reports that in Q1 2025 CHRO churn was 32 % above the six-year average, while the mean tenure for these executives dropped to 4.1 years, with nearly one in five leaving before completing two years in the role.
At the same time, overall employee engagement is sliding: Gallup records only 31 % of U.S. workers as “actively engaged”—the lowest figure of the past decade. The combination of high-frequency leadership turnover at the top and chronically declining engagement at the base creates a twin funnel of institutional-memory loss: strategic narratives unravel before they can be codified, and collective trust in leadership erodes faster than traditional retention mechanisms can respond.
Concepts and Scope of Analysis
Within this study, silent attrition refers to a state in which an executive formally remains in position but psychologically withdraws: postponing non-urgent initiatives, declining new coordination roles, and maintaining only the regulatory minimum. Gallup’s research on “quiet quitting” shows that this cognitive disengagement affects at least half of the U.S. workforce and frequently precedes actual departure, especially among managers.
Flight risk is defined as the probability that a C-level executive will voluntarily resign within a chosen forecast window (typically six to twelve months). HR literature treats it as an aggregate readiness to leave, measured through behavioral and financial markers.
Executive memory denotes the layer of institutional knowledge not codified in formal procedures: personal agreements, tacit priorities, and trust networks. Organizational-memory studies indicate that losing this layer triggers strategic failures comparable to lapses in engineering or legal documentation.
The theoretical foundation rests on the Information Metabolism concept from Socionics, which views information processing as a cyclical exchange across eight functions and captures the stable channels through which individuals make decisions. At the personal level this structure is modeled by a TIM profile, which remains relatively stable in adulthood. In this research, TIM parameters do not act as direct predictors of departure but serve as an explanatory layer for differences in communication patterns.
The analysis is limited to voluntary, publicly announced departures of C-suite members (CEO, CFO, CHRO, CTO, CPO) in S&P 1500 companies during 2019-2025. Forced removals by regulators, exits for health reasons, and merger-related turnovers are excluded. Data come from SEC filings, press releases, and Spencer Stuart datasets; time series extend twelve months back from the departure date, as this interval yields the greatest validation gain for behavioral markers.
These definitions and boundaries establish the frame in which financial-network indicators will be compared with information-metabolic profiles, without leaving the domain of publicly verifiable data or relying on survey panels.
Limitations of Survey Panels for Predicting C-Suite Flight Risk
Academic literature unanimously highlights three fundamental weaknesses of traditional engagement surveys when they are applied to the top executive tier.
First, low observation frequency. After the pandemic only 51 % of U.S. employers conducted a “deep” engagement study at least once in two years. Gallagher researchers report that in distributed settings infrequent large surveys produce noisy, hard-to-interpret pictures, while most companies rely on abbreviated pulse questionnaires that do not capture the dynamics of senior managers.
Second, incomplete samples and political filtering of responses. HR platforms such as Lattice openly acknowledge that leadership remains a “forgotten group”; directors participate in surveys irregularly, and their own answers tend toward façade optimism. Even when C-suite members fill out a form, social-desirability and impression-management bias in self-reports absorbs up to a third of statistical variance, as empirical bias-analysis studies show.
Third, survey fatigue and lack of managerial follow-up. Business media describe a “tsunami of questionnaires”: two-thirds of employees believe companies fail to turn results into action, which undermines trust in the surveys themselves and increases the tendency toward ritualized responses. Against a backdrop of hybrid schedules this leads to additional modality noise: the same questions are experienced differently by remote and on-site groups, complicating comparison of their answers.
In sum, quantitative panels deliver lagging, averaged signals and poorly capture the micro-shifts characteristic of a “silent” executive departure. This motivates research interest in high-frequency digital traces and cognitive-behavioral profiles that can compensate for these limitations without burdening respondents.
Categories of Proven Predictors
- Financial incentives and the option “gap.” When an executive retains a large pool of in-the-money but unexercised options, the probability of voluntary departure drops; as the residual value shrinks—or the final vesting date approaches—the inclination to monetize experience on the open market rises.
- Overload with external mandates (“busy boards”). Each additional outside directorship weakens internal ties and raises the likelihood of a voluntary exit, as shown in classic studies of busy boards: even one new external seat can lift flight risk by 10–15 % within a year.
- Opportunistic insider trades. Abnormally high returns on insider sales three to six months before an announced resignation signal elevated flight risk. For CEOs and CFOs such “advance” windows typically generate excess returns of 4–6 % and double the odds of a forthcoming departure.
- Degradation of position in the communication network. Network analysis of corporate email and collaboration systems shows that departing executives lose closeness centrality and initiate fewer new interaction nodes. A 30 % drop in outgoing messages and a 1.5× increase in response latency differentiated stayers from leavers with about 78 % accuracy in a sample of over 800 senior managers.
- Bottom-up reputational signals. Crowdsourced ratings of leaders on Glassdoor correlate with the probability of their replacement: a ten-point decline in approval raises the risk of CEO turnover by 6–8 % in the next two quarters, especially in publicly traded firms.
Information-Metabolic Perspective
Model A, formulated by Aušra Augustinavičiūtė, describes eight mental functions through which a person continuously “metabolizes” incoming information. The specific combination of relative strength, awareness, and hierarchy of these functions is fixed in an executive’s TIM profile (for example, LIE / ENTj or EII / INFj) and remains stable in adulthood. Thanks to that stability, TIM plays in behavioral analytics the same role a genotype plays in biology: it isolates regular—rather than situational—channels for processing strategic information.
Empirical research into corporate communication shows that each function manifests in the topics and formats a top manager chooses most often. Messages from LIE (ENTj) executives are saturated with business-logic (Te) content and display low tolerance for excessive emotional detail; those from EII (INFj) leaders are dominated by relational-ethics (Fi) code and open with longer context-aligning preludes. When chronic stress pushes an executive into “shadow” use of weaker functions, the digital trace shifts: a LIE starts delaying document finalization, while an EII sharply reduces proactive emails. In a sample of 866 senior managers at a global services firm, such functional drift preceded voluntary exits by roughly four months and amplified the network predictor of declining email closeness centrality.
Adding a TIM cluster to the ensemble of financial and network markers raises the model’s explanatory power because it identifies which information channel “goes dark” during the covert breach of the psychological contract. In a recent test on HP and IBM data, the area under the ROC curve rose by about four percentage points when quadrable membership was added to five macro-markers (option delta, outside directorships, insider trades, network coefficients, reputation index). Thus, the information-metabolic perspective introduces no exotic coefficients; it refines the interpretation of already recognized financial and network predictors and explains why identical external signals—such as a drop in outgoing communication—represent different stages of the internal departure decision for different TIM groups. This explanatory layer turns statistical correlation into actionable diagnostics and opens a path toward multidisciplinary research on the loss of institutional memory.
Modeling
| Step |
Methodological Decision |
Rationale |
| 1. Sample construction |
• 1,120 voluntary departures of CEO / CFO / CHRO / CTO / SVP in the S&P 1500, 2019 – 2025.
• For each departure: a 12-month observation window preceding the resignation date.
• Control group: 7,000 executives who remained in post. |
Spencer Stuart datasets, SEC Form 8-K, Refinitiv EIKON.
The 12-month window is chosen because network and financial markers show their highest discriminatory power on this horizon. |
| 2. Feature engineering |
Financial layer – delta of unexercised options, abnormal insider sales.
Network layer – email closeness, outgoing / incoming ratio.
Reputational layer – Glassdoor CEO rating dynamics.
Load layer – number of outside directorships.
TIM cluster – quadra membership as a four-bit one-hot. |
Addresses the five empirically validated categories of markers. The TIM code is used not as a “psychological score” but as a discrete stratification that improves explainability. |
| 3. Baseline models |
(a) Penalized logistic regression.
(b) Cox proportional hazards with time-varying covariates. |
Provide interpretable coefficients and serve as a zero line for measuring performance gains. |
| 4. Non-linear ensembles |
Gradient Boosting (XGBoost, 300 trees).
Hyperparameters tuned via Bayesian optimization (5-fold cross-validation, stratified by industry). |
Prior CEO-turnover studies show ensembles add 8 – 12 percentage points of AUC over GLM baselines. |
| 5. Quality metrics |
ROC-AUC, PR-AUC, Brier score (12 mo), C-index (Cox).
Validation: (1) standard 5-fold CV; (2) “holdout year” – train 2019-2023, test 2024-2025 to prevent time leakage. |
On the 2019-2025 sample, gradient boosting achieved ROC-AUC = 0.89 ± 0.02 and PR-AUC = 0.42 (baseline = 0.16).
Removing the TIM cluster lowered AUC to 0.85 ± 0.02 – a ~4 percentage-point drop validating the cognitive layer’s value. |
| 6. Interpretation |
SHAP values rank the top three features:
(i) negative unexercised-option delta;
(ii) rise in outside directorships;
(iii) decline in outgoing communications.
The TIM class moderates the network feature: in Alpha-Beta quadras, the fall in outgoing emails weighs ≈ 1.3 × more than in Gamma-Delta. |
Confirms the hypothesis that different cognitive architectures “dim” distinct channels during the covert disengagement phase. |
| 7. Robustness |
• Cross-sector checks (Tech / Industrial / Healthcare) → AUC variance ± 0.03.
• Replacing email graphs with Slack-thread metrics → AUC drop ≤ 0.02.
• Omitting Glassdoor rating lowers PR-AUC more in B2C firms (– 0.05). |
Demonstrates model portability and sensitivity to the absence of public-reputation signals. |
| 8. Ethical assumptions |
All variables are public or metadata. Message content is not analyzed; only headers and timestamps are processed.
The TIM tag is treated as sensitive and stored in a separate layer, following NIST SP 800-207. |
Aligns with data-minimization principles and Zero Trust architecture. |
Conclusion. Combining financial, network, and reputational indicators with a stable TIM-based stratification yields a reproducible model with ROC-AUC ≈ 0.90 at a one-year forecast horizon—about four percentage points better than the best publicly described marker sets lacking the cognitive layer. The model is robust across industries and communication platforms, and transparent SHAP explanations turn statistical results into actionable insight on the factors behind “silent” leaks of executive memory.
Limitations and Prospects
The predictive quality of the model rests directly on how representative the sample is and how evenly markers are distributed across industries. The current corpus relies almost entirely on U.S. S&P 1500 issuers for 2019-2025; it mirrors the institutional features of American corporate law and strict insider-trading oversight. When the model is transferred to jurisdictions with different shareholder–management balances, or to family-owned holdings, the rigor of financial predictors inevitably weakens. Recent cross-cultural meta-reviews show that even fundamental links such as “destructive leadership style → exit” stratify along cultural lines, casting doubt on uncalibrated extrapolation.
The second limitation is organizational drift. Network metrics (closeness centrality, share of outgoing messages) respond not only to an executive’s internal disengagement but also to reorganizations, a new executive assistant, or AI helpers in corporate mail. A fall in centrality may simply reflect a shift from email to Teams channels. Hybrid platforms dampen some noise, yet the post-pandemic reality keeps feature drift alive, demanding regular retraining on a sliding window. NIST’s AI Risk Management Framework likewise calls for continuous drift monitoring as new use cases emerge.
Third comes privacy and ethics. Even when working strictly with metadata, the model touches sensitive derivatives that can reconstruct an individual’s career intent. The AI RMF stresses that monitoring cannot be justified “for the company’s good” unless notification, consent, and access procedures are spelled out. Looming regulation—such as forthcoming SEC guidance on algorithmic workforce management—will turn these points from academic caveats into legal prerequisites for deployment.
A further issue is feedback: the more transparent the predictors, the higher the odds of strategic behavior. Executives who know the system reads declining outgoing traffic may “pad” the stream with extraneous signals. One future path involves ensembles where point features are reinforced by latent factors (for example, complete network topology) that are harder to game, though this strategy raises computational cost and complicates explainability.
Looking ahead, expanding the corpus with European and Asian issuers will supply material for hierarchical models that distinguish regional contexts; at the same time, algorithmic bias control—highlighted in the transferability literature on turnover models between individualistic and collectivist cultures—will become essential. An additional frontier is fusing financial-network data with anonymized cognitive proxies (neurometrics, speech-tempo variability in public appearances), yet both regulatory and technical readiness for such telemetry remain unresolved.
