One’s consciousness is not necessarily the only determinant of the brain’s functionality. It is possible, as Kahneman argues, to process several computations in the mind even when someone is momentarily at rest or unconscious. This chapter elucidates the ease with which the brain functions and derive a conclusion based on events. Kahneman makes significant attempts to differentiate cognitive ease with cognitive strain, which in effect determines the processing capacity of an event or action. Also, the chapter highlights the factors that determine one’s ability to remember an occurrence. Kahneman employs previous works by several authors on the cognitive ease to explicate its essence in the mind study.
