Quite easy – if you’re a gum-chewing, coffee-guzzling daydreamer with incredible self belief...
Drink coffee after a task. Boosts your chances of remembering it, as does chewing gum or doodling while you do it.
Listen to music you like. This increases dopamine levels, thought to improve cognition.
Daydream. Daydreamers do better on tests than their more focussed peers.
Exercise. Increases the level of a protein in your blood that promotes the growth and formation of new neurons. Eat brain-friendly food. Food with Omega-3 fatty acids like fish, as well as B vitamins (in green veg, milk and shellfish), are thought to maintain brain function.
Clean your teeth properly. Having no teeth is linked to degenerative cognitive functions.
Really long term:
Stick around. Over a series of decades, IQ scores have got better and better, meaning that, simply because of when you were born, you’re probably smarter than your great grandmother.
And a super easy short-term fix...
Studies have shown that just believing you can be smarter actually makes it come true.
