Why Public Commitments Cut Both Ways

Telling people about a goal is standard advice and is also warned against. Both positions have support, because announcements do two different things depending on how they are made.

Announcement can substitute for action

Stating an intention produces recognition from others, and recognition supplies some of the satisfaction that achieving the thing would.

Partially satisfied motivation is weaker motivation. The pressure that would have driven the behavior has already been partly discharged.

This effect is strongest for announcements about identity rather than about actions. Being seen as someone who is writing a book is available immediately; writing it is not.

Commitment works through cost

The version that helps operates differently. It creates a specific consequence for not doing the thing, usually the awkwardness of a known failure.

That consequence has to be real. Telling a large audience with no follow-up creates almost none, while telling one person who will ask about it creates a lot.

Accountability of this kind depends on the checking rather than the telling, which is why broad announcements are the weakest form.

What is announced determines which effect applies

Announcing an outcome invites recognition for the ambition. Announcing a process invites checking on whether it happened.

Because a process is verifiable, it cannot be satisfied by the telling. Nobody congratulates someone for intending to run on Tuesdays.

The distinction explains most of the conflicting advice. The studies and the experience differ largely on this variable.

The audience matters more than the size

Commitments made to people whose opinion carries weight, and who will encounter you regularly, generate durable pressure.

Commitments broadcast to people who will never mention it again generate an event rather than an obligation.

One person who asks each week does more than a hundred who saw a post, and the second option is considerably more comfortable, which is why it gets chosen.

The cost of a public failure

Public commitment also makes abandoning the goal expensive, which is the intended mechanism and occasionally the problem.

Goals that should be dropped are harder to drop once announced, and the pressure that keeps someone going does not distinguish good persistence from bad.

Announcing the review rather than only the goal handles this. A commitment that includes a stated point at which it will be reconsidered keeps the pressure without removing the exit.
