The reality check

What the machines actually did with 10, across every lottery this site holds a long record for.

Powerball95of 103 expected−0.77σ
UK Lotto118of 119 expected−0.12σ
EuroMillions117of 104 expected+1.31σ
SuperEnalotto163of 161 expected+0.17σ
Set for Life365of 378 expected−0.73σ

Across 5 lotteries that hold a 10, its average deviation from expectation is −0.03σ. Statistically ordinary, everywhere.

The one thing a belief about a number can measurably do is change how many people play it — and a jackpot shared more ways is worth less to each winner. That is the only real consequence, and it is arithmetic rather than folklore.
