Preserved self-other integration during social decision making among individuals with elevated autistic traits
Through four large-scale experiments, this study demonstrates that variations in autistic traits do not significantly impact self-bias or the use of social basis functions during social decision-making, challenging traditional assumptions about self-other integration deficits in autism.

Imagine your brain as a busy control room that constantly has to balance two types of information: what you know about yourself and what you know about other people.
For a long time, experts thought that people with high autistic traits had a "glitch" in this control room. The old idea was that their system struggled to switch between their own perspective and someone else's, making social interactions feel like trying to navigate a maze with a broken map.
However, this new study decided to test that map with a much bigger, more powerful flashlight. The researchers gathered a massive group of over 1,600 people and ran four different experiments to see if autistic traits actually change how people mix "self" and "other" information when making social choices.
They looked at two specific things:
- The "Self-Bias": Do we naturally prioritize our own feelings and needs over others? (Like a GPS that always highlights your home first).
- The "Social Basis Function": Do we use shortcuts or patterns to understand how people usually interact? (Like using a pre-loaded weather app to guess if you need an umbrella, rather than staring at the sky for hours).
The Big Surprise
After crunching the numbers with very strict statistical tools (called Bayesian analyses), the researchers found no difference at all.
Think of it like this: If you line up people with low autistic traits and people with high autistic traits side-by-side, their "social control rooms" are running on the exact same software.
- They prioritize their own needs just as much as anyone else.
- They use social patterns and shortcuts to make decisions just as efficiently as anyone else.
The study found strong evidence that the "glitch" theory is likely wrong. Instead of a broken map, the brain's ability to integrate self and other information seems to work perfectly fine across the entire spectrum of autistic traits.
Why This Matters
The researchers emphasize that they needed a huge group of people (1,621 participants) to be sure of this result. With smaller groups, you might accidentally think there's a problem when there isn't one. This study proves that, at least regarding these specific social decision-making skills, autistic traits don't change the fundamental way people process themselves and others. It suggests we need to rethink how we understand social thinking in autism, moving away from the idea of a deficit and looking at the strengths and similarities we all share.
