Numerous people don’t realize this or that there’s not some simple consistent blood test to say “yep, he’s got autism.”

Moreover, people have no idea how difficult this makes it to properly test anything related to it because control groups are so difficult. It’s why any type of study that claims something does or does not, definitively “cause autism” is highly unlikely.

You can identify potential contributors, but that’s about as good as it gets.

People in absolutes about this stuff can’t be taken seriously.
