When the coronavirus outbreak hit cleaning products and hand sanitizer became a rare find but the toilet paper shortage didn't make as much sense.
Now researchers are looking at why it was on the panic-buying list. Data was collected from the United States and across Europe. They found people with conscientious personalities were more likely to panic-buy toilet paper. That means people who are more organized and like to plan ahead.
Researchers say panic-buying is also contagious because humans often look to each other for cues on what is safe. They believe this could be what led to widespread toilet paper demand.
