Can family guess the gender?

Every guest picks team pink (girl) or team blue (boy) when they join. Across 109 guesses, 54 were right: 50%. Hunches, bump shape and old wives' tales don't do better than chance. If your family wants to try anyway, the old wives' tales quiz and the Chinese gender predictor are fun, as long as nobody takes them seriously.

Where the parties were

Parties were hosted from 17 countries and played in 6 languages. Guests often join from other countries than the host.
