Saiki adds an experimental behavioral signal derived from your recent League matches alongside the questionnaire, so you can see where gameplay patterns and self-report answers agree or diverge.

Players are naturally engaged while gaming, eliminating test anxiety and social desirability bias that often skew traditional assessment results.

Track changes over time through ongoing gameplay, rather than single-point assessments that may not reflect your typical cognitive state or personality.

A University of York study (Kokkinakis et al., 2017, PLoS One) found a significant positive correlation between League of Legends rank and fluid intelligence measured under controlled lab conditions. The age profile of MOBA performance mirrors the age profile of raw fluid intelligence, and the authors suggest commercial games could serve as population-level proxy tests of cognitive performance. This research informs Saiki's in-development cognitive-ability feature; Saiki does not currently provide an IQ score.

A 2022 study (Sauce et al., Scientific Reports) tracked approximately 9,855 US children from ages 9-10 over two years. Children who played more video games than average were associated with gaining about 2.5 IQ points more than average over that period, after controlling for genetics and socioeconomic background. TV and social media showed no similar positive effect. The authors describe this as an association, not proof of direct causation.

A 2022 study published in JAMA Network Open (Chaarani et al., approximately 2,217 children) found that video gamers performed better on response-inhibition and working-memory tasks, with associated differences in brain activity patterns. This is an association study; the research does not establish that gaming caused the differences observed.
