16 missed penalties so far (in-game and shootouts), already higher than 14 missed in 2022 WC. Why is it so hard to score one suddenly?

The 2026 World Cup has already set a new record for the most missed penalties in tournament history.
Including both in-game penalties and penalty shootouts, there have been 16 misses from 51 attempts (31.4%), surpassing the previous record of 14 misses at the 2022 World Cup, and there are still 13 matches left to play.
