The Anchor Effect

People are often anchored to an initial piece of information.

Why it matters

People become irrationally anchored to the first piece of information that they see.

i.e., in a sales negotiation, the person who first suggests a price has anchored the barter around that value.

In the above illustration, the second option would likely feel like a better deal, because the 'value' of the shoe has been anchored at $900, despite there being a sale price.
