Recent studies suggest that no matter your age in life, there's almost always a new peak in regards to intelligence on the horizon.
If you think you've already witnessed the rise and fall of your peak self, researchers have news for you: As far as your intelligence is concerned, you likely have several new highs to look forward to. Some of them, like the ability to read others' emotions or do basic arithmetic, don't arrive until middle age or beyond.
A team lead by Joshua Hartshorne, an MIT cognitive science researcher and the lead author of a study looking at how intelligence changes as we age, quizzed thousands of people aged 10-90 on their ability to do things like remember lists of words, recognize faces, learn names, and do math. Their results suggest that no matter your age, there's almost always a new peak on the horizon.
