A survey conducted by OnePoll on behalf of Jif ahead of National Peanut Butter Day found that the differences between those who love creamy peanut butter versus crunchy peanut butter are vast. The survey questioned 2,000 individuals, a group that was split down the middle by crunchy or creamy peanut butter preference. OnePoll found that one-third of people described themselves as being "passionate" about their peanut butter preference. Other conclusions suggested that people who like creamy peanut butter best were also more likely to be introverts and early risers while crunchy lovers were extroverted and night owls. There's one thing all peanut butter lovers can agree on despite what side of the aisle they're on, though...grape jelly over strawberry jelly in a PB&J.
