You can often tell if a person has autism by their visible or physical traits. Is this statement true or false?

The statement is false because autism spectrum disorder (ASD) is primarily characterized by challenges in social interaction, communication, and behavior, rather than distinct physical traits that are universally observable. Individuals with autism may exhibit a wide range of behaviors and abilities, and the condition does not manifest through specific visible or physical characteristics.

While there may be some instances where individuals with autism exhibit certain traits that could be perceived as common among them, such traits are not definitive indicators of the condition and can vary significantly from person to person. Additionally, many individuals with autism do not display any observable traits that could lead to identification based solely on physical appearance. Therefore, one cannot reliably determine if a person has autism just by looking at them, making the statement fundamentally inaccurate.
