- Too 12y agoThis one is actually true and interesting for real. If you haven't heard of this before i highly recommend reading up about it. When measuring random things in nature, regardless of what unit and base you use to measure (inches, cm, m, feet, etc), measurements with lower first digit appear more frequent than others! This is due to things in nature usually being exponentially distributed, when you have an exponential distribution you will "move away" faster from higher valued digits and reach the next power of ten faster, there you will restart with a low first digits which is slow to move away from. For example, assuming a spread of about 50%, then 1+50%=1.5 (still starting with 1) but 5+50%=7.5 (not starting with same digit), and 8+50%=12 (starting with 1 again).
