Mental Set Definition | Psychology

A mental set is when people attempt to solve problems in a similar way as the past, even though they might not have an optimal or effective approach. It’s the tendency to approach a situation or problem in the same way because something similar may have worked in the past.

Think of how often people try to push open doors at shopping malls just because they’re used to pushing open doors more often than pulling them. Of course, one could just stop and read the one-word sign first, but that’s just so much work, right?
