Autistic adults show enhanced generosity to socially distant others.
Autistic adults give more to strangers and stick to fair splits, so tap their built-in fairness rules during social skills training.
01Research in Context
What this study did
O'Connor et al. (2024) asked autistic and non-autistic adults to split money with strangers, friends, or no one.
The team used a simple computer task in a quiet lab. No one watched the choices, so reputation did not matter.
Each adult decided how much of a small cash pot to keep and how much to give away.
What they found
Autistic adults gave more money overall than non-autistic adults.
The extra giving came from bigger shares to strangers and steady fair splits no matter how close the other person was.
Non-autistic adults gave less to people they did not know, showing the usual social-distance drop-off.
How this fits with other research
Ghosn et al. (2025) saw the same fairness focus in autistic youth. Kids took longer to decide and made fewer selfish offers, showing the rule "be fair" starts early and grows stronger.
Townsend et al. (2021) looks like the opposite result: autistic preschoolers shared toys the same as typical peers. The gap appears later, so fairness norms may bloom with age in autism.
Cage et al. (2013) found autistic adults only gave more when they expected something back. O'Connor et al. (2024) removed that cue and still saw generosity, updating the picture: autistic adults can give freely, not just for reputation.
Why it matters
You can stop assuming clients will always be stingy or self-focused. When you teach social skills, highlight their natural fairness as a strength. Use clear, explicit rules like "share half" in group work. Let older autistic learners take an extra moment to decide—they may be running a fairness check, not stalling.

03Original abstract
Autistic people show differences in their social behaviour. But how autism affects decisions to share resources, an important part of cooperation, was previously unclear. In our study, participants made decisions about how to share money with different people, including people they felt close to, such as a friend, and people they felt less close to, such as a stranger. We found that compared to a group of non-autistic participants, autistic adults shared more money overall and this was driven by greater generosity to strangers. The results suggest that autistic adults were more generous because they made fair decisions (an equal split of the money) more consistently regardless of how close they felt to the person they were sharing with. By showing that autistic adults display greater generosity, our results could help to change public perceptions of autism and potentially improve opportunities for autistic people.
