It's a math term whose meaning depends on the qualities of the other people around you, not a reference to any one particular set of characteristics: https://en.wikipedia.org/wiki/Normal_distribution
"Neurotypical" is the more current and precise term when discussing human behavior, cognition, or neurodevelopment. "Normal" is vague, value-loaded, and scientifically weaker because it implies that neurodivergent people are abnormal rather than simply different. In this context, "neurotypical" is clearer language.
