I'm sure it's utterly wrong, but have a fascinating/weird anecdote: an ex-boyfriend's uncle (who I was relatively close to) was an engineer by training. I don't know what sort of engineer, but I know he started in manufacturing and moved on to consulting roles, and had a B.Eng. and some graduate credits (maybe a M.Eng.). He bought in to the whole "frequency" thing and purchased a very expensive box which he put on the back of his (very expensive) sports car's driver's seat.
The box was supposed to "negate" the negative frequency caused by driving. When his nephew (an M.Eng.) asked him what was in the box, he explained that you would negate the effects if you opened the box, so he just trusted in it.
