You like to be­lieve what you think is ra­tio­nal. You like to be­lieve that you are not one of those mis­guid­ed peo­ple who be­lieve crazy stuff.

Well, sor­ry, you are. As an ex­am­ple, I will pro­vide two su­per­sti­tions that will each look stupid to the per­son who be­lieves the oth­er, and will both look stupid to the peo­ple who be­lieve nei­ther.

If you are from a coun­try of british her­itage, you may be­lieve cheese gives you night­mares. If you are in the British Cheese Board, you may have paid for a study that claims that eat­ing Ched­dar will make you dream of celebri­ties.

Al­so, the of­fi­cial Ched­dar An­them:

On the oth­er hand, if you are from South Ko­re­a, you may be in­clined to be­lieve that sleep­ing with an elec­tric fan turned on is dan­ger­ous, and may cause you as­phyx­i­ate, or suf­fer hy­pother­mi­a.

Al­so:

If both of these sound ab­surd to you, keep in mind that you prob­a­bly hold some be­lief just as ab­sur­d, but don't know it.
