I like to make up my own tests, that way you know it is actually thinking.

Tests that require thinking about the physical world are the most revealing.

My new favourite is:

You have 2 minutes to cool down a cup of coffee to the lowest temp you can.

You have two options: 1. Add cold milk immediately, then let it sit for 2 mins.

2. Let it sit for 2 mins, then add cold milk.

Which one cools the coffee to the lowest temperature and why?

Phrased this way without any help, all but the thinking models get it wrong
