The evidence beneath better decisions

Every article here is anchored to a real experiment — Wegner's white bears, Asch's lines, Simons and Chabris's gorilla — and traced through to what it means for how your organisation decides, designs and performs.

The White Bear Effect: Why Telling Your Team Not to Worry Guarantees They Will

Wegner's 1987 thought-suppression experiments explain why reassurance during organisational change so reliably backfires — and what to say instead.

The Stroop Effect Is Sitting In Your Dashboard, Charging Interest

A 1935 experiment with coloured words explains why your operations dashboard slows people down — and why adding clarity usually means removing information.

Miller's Law and the Seven-Option Meeting That Decides Nothing

Working memory holds far less than most strategy processes assume. Miller's 1956 paper explains why long option lists produce worse decisions, not more thorough ones.

The Number You Say First Wins: Anchoring in Budgets and Forecasts

Tversky and Kahneman showed in 1974 that a demonstrably random number shifts expert estimates. Your budgeting process is probably built on this flaw.

Asch's Lines: What Your Meetings Are Actually Measuring

A 1951 experiment with three lines on a card explains why consensus in your leadership meetings may be an artefact of seating order rather than agreement.

Evidence: The Asch Conformity Experiments, 1951

Confidence Is Not a Competence Signal: Reading Dunning and Kruger Properly

The 1999 study is widely cited and widely misused. What it actually shows has direct consequences for how you interview, promote and assess capability.

Evidence: Unskilled and Unaware of It, 1999

The Forgetting Curve: Why Your Training Budget Evaporates in a Fortnight

Ebbinghaus mapped memory decay in 1885. Corporate learning has spent well over a century designing as though he never published.

Extraneous Load: The Tax Your Processes Charge Before Work Begins

Sweller's cognitive load theory separates the difficulty of the work from the difficulty your systems add to it. Most process improvement targets the wrong one.

Automation Bias: The Failure Mode Your AI Rollout Is Currently Building

Skitka's 1999 experiments showed that people miss events they would otherwise catch when an automated aid is present. This is the central risk in AI adoption.

Decision Fatigue and the Cost of Scheduling Hard Calls Badly

A 2011 study of parole rulings suggested judgement degrades across a session. The finding is contested — and the operational lesson holds either way.

Same Numbers, Different Decision: The Framing Effect in Strategy

Tversky and Kahneman's 1981 Asian disease problem showed that logically identical options produce opposite choices. Your strategy papers are framing devices whether you intend them to be or not.

The Gorilla in Your Control Room: Inattentional Blindness in Monitoring Work

Half the observers in Simons and Chabris's 1999 study missed a person in a gorilla suit. Your monitoring roles are built on the assumption they would have noticed.
