According to the latest scientific survey, people who like crunchy peanut butter might have a cheerier outlook on life than those who prefer creamy.
It’s not a huge margin, but 63% percent of people who prefer crunchy described themselves as optimists, compared to 56% of those who prefer creamy.
Fans of the creamy also tend to be early birds and more introverted – whereas fans of the crunchy are more likely night owls and extroverts.
