Justifying a decision: what accountability really changes
Within an organisation, having to explain a decision can encourage consideration of alternatives or merely the search for arguments acceptable to senior management. The managerial question is therefore precise: under what conditions does having to justify a choice improve thinking before the decision?
What the literature establishes
Philip Tetlock (1983, Journal of Personality and Social Psychology) experimentally investigated the effects of accountability on the complexity of reasoning. When participants expect to justify their judgement to someone whose views they do not know, their thinking can become more complex, distinguishing and integrating a wider range of perspectives. This finding concerns a characteristic of reasoning, not a guarantee of a correct decision.
The recipient of the explanation changes the mechanism
Jennifer Lerner and Philip Tetlock (1999, Psychological Bulletin) show in a literature review that accountability is not an intervention with uniform effects. When the recipient's preferences are known, anticipating the need to justify a decision can encourage alignment with those preferences rather than open-minded consideration. When accountability comes after a commitment, it can also encourage the defence of a choice already made.
The premature conclusion
It might follow that simply requiring a written justification will improve decisions. The cited research does not support that conclusion: a document can serve either to explore trade-offs or to dress up an established preference. The useful distinction concerns the timing and purpose of the justification, not merely its existence. (our executive and employee training programmes)
What the evidence cannot promise
The experimental settings and the studies assembled in this review do not demonstrate that a particular procedure will reduce qualification errors in a Neuchâtel industrial company. More complex thinking may clarify a trade-off without resolving technical uncertainty. Likewise, the presence of a rationale in a file proves neither its independence from management preferences nor its actual influence on the choice.
A practical check in Neuchâtel
As part of SHR's decision-making programme, an exercise applicable to a Neuchâtel company in microtechnology, watchmaking or precision microelectronics is to document supplier qualification decisions before approval. For each file, record an alternative considered, a technical trade-off and a remaining uncertainty, then date the note before the approver announces a preference. Over a period defined in advance, measure the proportion of decisions with this prior note, checking both timestamps and content. This indicator verifies a discipline of deliberation; it does not, on its own, demonstrate improved decision quality.
