This site documents a single, measurable fact: performances that represent the absolute peak of women's athletic achievement are routinely surpassed by male athletes at the high school and youth level. Every comparison uses the same sport, the same event, and the same units — no cross-sport conversions, no adjusted standards.

The Track & Field and Other Sports pages show specific data points: world records compared to high school or junior results. The Impact page models a hypothetical — if X% of US high school boys entered women's competition, where would today's world record holders rank? That is a statistical model with real uncertainty; the other pages are direct factual comparisons.

Why team sports are not included. Major professional leagues — NBA, WNBA, NHL, PWHL, NFL, MLB, NWSL — were evaluated and excluded. Team sport statistics are inherently context-dependent: pace of play, opponent quality, roster construction, and structural rule differences (women's hockey bans body checking; basketball uses different ball sizes) all shape the numbers in ways that cannot be isolated. A shooting percentage or a save percentage reflects the competition environment as much as the individual athlete. This site only includes comparisons where both athletes are performing the identical task under identical conditions — the same distance, the same implement, the same rules — so that the numbers speak for themselves without requiring adjustment.

The slider on the Impact page represents the share of the total US high school boys population for a given sport who would theoretically enter women's competition. At 0% nothing changes. At 10% of the track pool, that is 64,424 boys.

Male performance in each event is modeled as a normal distribution with a mean and standard deviation estimated from published competition data. We then calculate what fraction of that distribution would beat a given women's mark, multiply by the number of boys competing, and add that count to the woman's original rank.

The total US high school boys outdoor track & field population is 644,235 (NFHS 2024–25 participation survey). Distribution parameters by event:

Jump events carry higher uncertainty than sprint events because the full-population distribution is harder to measure — many HS athletes compete in jumps secondarily. Parameters are anchored to state-qualifier entry standards and NFHS All-American lists.

Shot put, discus, hammer, and javelin are now included as elite-to-elite comparisons (men's senior world record vs. women's senior world record), not distribution-modeled comparisons. In three of four events — shot put, javelin, and hammer — the men's world record exceeds the women's world record in raw distance, despite men using heavier implements. In the fourth event (discus), the women's world record (76.80m) is 1.24m longer in raw distance, but men throw a disc twice as heavy (2.00 kg vs. 1.00 kg).

The direction of bias is known and consistent: men's marks systematically understate their advantage because heavier implements reduce achievable distance. If men used the lighter women's implements, every gap shown would be larger. Throw events are therefore a conservative floor, not an outlier.

The distribution model used for track and jump events cannot be applied to throws — no sufficiently large, standardized dataset of US high school boys' throw marks exists to build a reliable mean and SD. The HS boys marks shown in the Impact section use standard boys' implement weights and cannot be directly compared to women's marks set with lighter implements.

Each sport in the Beyond Track & Field section uses its own male participant population (not the 644,235 track total) and its own estimated distribution.

The Impact model is a statistical estimate, not a prediction. Normal distributions are approximations — actual male athletic performance is right-skewed (more elite outliers than the model predicts at the high end, more non-competitive participants at the low end). The true displacement could be higher or lower depending on how the actual distribution deviates from normal.

Estimated distributions carry real uncertainty. Events marked "Estimated" use parameters derived from known anchors (state qualifying standards, All-American lists, national top-10 data) rather than full empirical datasets. The 200m, 800m, 1500m, 5000m, and all jump events fall into this category. Treat those results as directionally correct, not precise.

The swimmer pool/format conversion introduces uncertainty. US high school boys primarily compete in 25-yard (SCY) pools. Women's world records are set in 50m (LCM) pools. Converting between the two formats involves a known approximate adjustment (~7–8%) but individual variation means some boys near the threshold could be on either side.

Participation ≠ competition readiness. The NFHS participation total includes all boys who competed in at least one event during the season — not all are trained specialists in the events shown. The model's use of the full population rather than event specialists is intentional (it answers the "what if boys were allowed to enter" question, not "what if only elite boys entered"), but it means the results should be read in that context.

Women's marks used throughout are world bests, not averages. This site compares the absolute peak of women's performance — not average women's performance — to high school boys. The point is not that random boys beat random women. It is that performances representing the ceiling of women's athletic achievement are surpassed by teenage boys competing at high school or junior level.
