There's a method of calculating the value of a mathematical function that starts with a guess of the value, and then iteratively tries to improve it. It works fine as long as the initial guess is good enough, but there are some functions where if the initial guess is wrong, it appears as if the function converges on the answer, but it is in fact only a local optimal value, and not the optimal value. Designing a user interface can be similar. People don't behave as we expect them to, so we make a first guess at an interface…
