Adverse Selection

Health insurers suffer from a well-known phenomenon called adverse selection, where people who are the most likely to suffer claims are the most likely to purchase the insurance.

I think there is a similar phenomenon in parenting. This is where Pete is most likely to ask for help with something at the most difficult or desperate times. So let's suppose (hypothetically) he is building a clawing lobster. He will ask you to help with the piece that requires the most supreme amount of strength and finesse, but of course without applying too much force (which would destroy the entire infrastructure of the model). Also, it is also assumed that you are instantly familiar with the full schematics of this item that you have never seen before.
