A probe that began with an intriguing question – when does our intelligence peak? – lays bare some really fascinating aspects about this human attribute. The researchers, who set out to pinpoint the crest of our intelligence, luckily had many answers and none, for they found that our intelligence – a combination of our cognitive ability and expertise – has many facets, which peak at different ages.

For example, a comprehensive study and analysis found that our ability to assess people’s emotions tops out in our 40s or 50s, our short-term memory primes at around the age of 25 and the speed of information processing peaks at around 18 or 1, writes Quick and Dirty Tips.

What contributes more to the abstruseness of the subject is that our intelligence can be divided into fluid intelligence and crystalline intelligence, which have their own distinct pace of maturity and decline, reports Scientific American.
