The key to approaching coin flips, I’ve often found, is having utmost confidence that you’ll call heads or tails correctly.
I feel like when I call “heads” in a voice as serious and assertive as I can muster, I’m almost willing the coin to land George Washington-side up. I’m influencing the very universe itself, the atoms inside the coin and the wind blowing it as it flips through the air, to land on my desired outcome.
This, of course, has no impact on what side the coin will land on (at least not provably). The whole idea behind a coin flip is that it’s 50-50.
