Abilene Paradox, explained.
The Abilene paradox describes a group taking an action contrary to members' private preferences because they mismanage agreement and misperceive what others want.
Why it happens
Four fictional colleagues privately prefer staying but publicly agree to an overnight trip. Choose to agree or request private preferences. The first path books the trip; the second reveals unanimous private opposition and cancels it. Inspect the belief ledger behind the public yeses.

Read the result
The final trip decision follows your information procedure. Read the belief ledger to see how public yeses can coexist with unanimous private opposition.
A worked example
A trip approved by people who prefer staying
Choose whether to agree to the proposed trip or first ask each fictional colleague for a private preference.
Run the meeting and inspect the all-stay private preferences alongside the reasons given for public agreement.
The private-poll path cancels the trip; the agreement path books it. Both outcomes come from the same stipulated preferences.

Inside this model

Where this idea is useful
A practical use
Before treating silence or polite consent as support, a team can ask what each member independently prefers.
A common misconception
“Unanimous public agreement always represents unanimous preference.”
People may assent because they misread others' wishes. Harvey's example concerns managing agreement, not a universal claim that consensus is dishonest.
What this explanation leaves out
- This is one stipulated all-opposed scenario, not a prediction that apparent agreement is always false. Private responses can reveal sincere disagreement, constraints or pressure; the example does not diagnose a workplace.
How is this different from a real disagreement?
In the authored scenario everyone privately wants the same alternative. A real poll can instead reveal genuine competing preferences that require negotiation.
How would you make it easier to express an independent preference before hearing the group's apparent position?
