Why do people read reviews after buying something?
People seek reassurance long after decisions are made.
The purchase is finished.
The money is gone.
The decision cannot easily be reversed.
However, people still search for reviews.
The hidden mechanism is Borrowed Certainty. Decisions rarely end when actions end. Doubt survives surprisingly long.
Because of this, people seek confirmation from others. Positive reviews become emotional evidence that the choice was reasonable.
The object matters.
But confidence matters more.
People often think reviews help them decide.
Very often, reviews help them forgive themselves for deciding at all.
