Curse of Knowledge

Once you know something you cannot imagine not knowing it; experts overestimate what others understand, and buyers assume sellers have disclosed what seems obvious to the seller.

An everyday example

A contract clause that is 'standard' to the lawyer and invisible to the client.

What it can cost you

Communication that fails silently in both directions; assuming the counterpart shares your picture.

Warning signs

  • I assumed they knew.
  • They assumed I knew.

One thing to do

Explain as if to a newcomer; ask the counterpart to say back what they understood.
