Assuming boredom is not necessarily an inability to determine it, it may be an inability to accept a positive answer, as would be the case with poor self-esteem. Someone could of course both be autistic and have low self-esteem, and they may be related for complex reasons, but they aren't necessarily. This is why just taking random surveys without an expert is not a good way to diagnose.

In my experience, the most reliable informal indicator of autism is if basically all of your friends are diagnosed autistics. It's like that study where neurotypicals were able to point out the autistic person in a room simply based on whether they "feel different" - this ability to tell whether someone shares your way of thinking is actually common to most neurotypes, including autistic neurotypes. One typically ends up subconsciously selecting for neurotypes similar to their own when choosing who to make friends with. This isn't to say that they don't make friends with other neurotypes, just that they're more likely to make friends with similar neurotypes, and the majority of their friends are very likely to have similar neurotypes to their own.

Of course, going to a professional for a real assessment is the only thing I can really recommend. This would certainly be strong supporting evidence though, and meets my standard for self-diagnosis.

no i meant in a life spanning 20 something years I've only met two people who could talk to me for an extended time isn't that a good metric to use to say I'm boring like objectively?
