Considering 798 to be an odd number is endemic to human cognition, reveals a new study. A common assumption in the cognitive sciences is that thinking consists of following sets of rules (as it does in a computer). A recent research argues that unlike digital computers, which are designed to follow rules, the computations performed by the neural networks that make up our brain are inherently context dependent. People sometimes make seemingly strange mistakes like thinking that 798 is an odd number despite knowing how to identify odd and even numbers.
