We have so many mental frames related to numbers, that have been handed down culturally for, in some cases, hundreds and even thousands of years. These numerical superstitions come from myths, some from science, some cultural and historic — and many are universal. They remind us that despite our differences across nations and across time, we human beings still have a lot more in common with one another than we have differences.
