People often refer to someone as “left brain dominant” or “right brain dominant” as if there is some scientific evidence behind these patterns of behaviour. While the brain does have different functional areas on the left and right sides, that does not at all correlate to behaviour differences.
“Everyone should understand the personality types associated with the terminology ‘left-brained’ and ‘right-brained’ and how they relate to him or her personally; however, we just don’t see patterns where the whole left-brain network is more connected or the whole right-brain network is more connected in some people. It may be that personality types have nothing to do with one hemisphere being more active, stronger, or more connected,”
The point is that there are people who are more intuitive vs rational thinkers but this does not map to differences in brain activity.
