Our mind is more deep than you think
This phenomenon is referred to as transposed letter effect (or jokingly ‘typoglycemia’).
It describes the ability to understand words when the first and last letters are stable, but the intermediate letters are scrambled.
Your mind processes words as whole units, not letter-by-letter.
It works because our mind doesn’t just rely on what we see but also on what we expect to see based on the context provided by other nearby words.
