Simone Biles

Across three Olympic Games (2016, 2020, 2024) and six World Championships, became the most decorated gymnast in history, male or female: 11 Olympic medals and 30 World Championship medals, 23 of them gold. At the 2018 World Championships in Doha, she became the first American and only the tenth gymnast from any country to win a medal on every event at a single World Championships.

Four distinct skills across vault, floor exercise, and balance beam have been given the difficulty-rated name "the Biles" after her, at gymnastics' highest difficulty ratings — skills rated so difficult that, years after each was introduced, few or no other competitors have repeated them in competition.

On January 18, 2018, Biles publicly stated that former USA Gymnastics team physician Larry Nassar had sexually assaulted her and that USA Gymnastics had helped cover it up. She and other survivors were awarded the Arthur Ashe Courage Award later that year, and at the 2018 U.S. National Championships she wore a teal leotard in solidarity with other survivors of Nassar's abuse.

At the 2018 World Championships in Doha, Biles went to an emergency room the night before qualifying with a kidney stone, then won the all-around final by 1.7 points despite falls on vault and balance beam, and won the first-ever world title on vault with a new skill later named after her.

At the 2020 Tokyo Olympics, withdrew from most team and individual event finals after developing "the twisties" — a loss of spatial awareness while airborne that made completing her twisting skills unsafe — citing her mental health as the reason. The decision drew significant public criticism at the time from commentators who argued she owed her team a title defense regardless; it was more broadly reassessed within the following years as elite sport's institutions and press began discussing athlete mental health more openly. She returned to competition in 2023 and won Olympic all-around and vault gold again in 2024.

This is consistent with the profile's dual-edged proactive_agency score: a self-directed decision against strong institutional and public pressure to continue, whose reception shifted substantially between 2021 and her 2024 comeback. Proactive Agency
