A founder whose startup succeeded substantially because of fortunate market timing and broader industry tailwinds attributes that success almost entirely to their own specific strategic decisions and execution — a pattern consistent with the illusion of control, a well-documented tendency to overestimate one's own ability to influence outcomes that are actually determined substantially, or even primarily, by factors outside personal control.
The classic experimental research demonstrating this bias
Studies using simple, genuinely chance-determined tasks — predicting a coin flip, rolling dice — have found that factors giving participants an illusory sense of active involvement or personal choice, such as being allowed to choose their own lottery number rather than being assigned one randomly, increased participants' confidence in their own likelihood of a favorable outcome, despite the underlying outcome being determined by pure, unaffected chance regardless of any choice the participant made — a direct demonstration that active involvement itself, even when genuinely irrelevant to a chance-determined outcome, inflates a felt sense of personal control.
Why this bias applies with particular force to founders interpreting startup outcomes
A startup's actual trajectory is shaped by a substantial mix of factors genuinely within a founder's control — specific strategic decisions, execution quality, effort — and factors substantially or entirely outside that control — broader market timing, competitor actions, macroeconomic conditions, and considerable outright chance — and founders, having made many active, deliberate choices throughout the venture's development, are specifically well-positioned to experience exactly the illusion of control the underlying research describes, attributing outcomes heavily to their own active choices even when chance and external conditions played a comparably large or larger actual role.
Why this specifically distorts learning from both success and failure
A founder attributing a substantially luck-driven success entirely to their own specific strategic decisions risks drawing overconfident, potentially misleading lessons about which specific decisions actually drove the outcome, lessons that may not generalize well to a future venture where the same favorable external conditions and chance factors aren't present. The same bias can operate in reverse for failure, with founders sometimes attributing a substantially bad-luck-driven failure too heavily to their own specific decisions, drawing overly self-critical lessons that similarly may not reflect what actually determined the outcome.
Why this matters directly for how founders should approach future decision-making
A founder's confidence in a specific strategic approach, based heavily on a single past outcome that may have been substantially influenced by chance and external conditions, can lead to overconfident replication of that specific approach in a new venture facing genuinely different market conditions, a specific and consequential risk the illusion of control creates by inflating the perceived reliability of lessons drawn from an outcome that wasn't as purely skill-determined as it felt at the time.
What this means for founders interpreting their own past outcomes and planning future ventures
- Explicitly separate factors genuinely within personal control from factors substantially determined by chance or external conditions when reviewing a past outcome
- Be specifically skeptical of confident attribution of a strongly favorable outcome entirely to personal skill and decision-making, given how much market timing and chance typically contribute
- Consider how much of a past success or failure would likely have occurred under meaningfully different external market conditions, as a check on how much the outcome actually reflected personal control
- Draw lessons from past outcomes with appropriate humility about the role chance and external conditions played, rather than treating every outcome as purely and reliably attributable to specific personal decisions
The illusion of control is a genuinely near-universal bias, not a reflection of any individual founder's particular overconfidence — and recognizing its likely influence on how a founder interprets their own past outcomes is a meaningful, practical step toward drawing more accurate, more genuinely useful lessons for future decisions.
