> What do you think is causing the massive increase in autism seen in the US over the last few decades?

Tonnes of reasons. Parents being older before having children, spending your life surrounded by biologically active plastics (Hello, BPA, and its yet-to-be-banned cousins), changes in diet, Jupiter being in retrograde, etc, etc, etc.

Any one of them, even the wild-ass nonsense ones seem more plausible to me than one fraudulent study written by a doctor who wrote it in order to... Sell autism testing kits and litigation.

You should put less trust in proven, shameless liars, who have a simple explanation for all that ails you, that they will sell you a cure for.

The rates are significantly greater in the US than in Europe. (As are the number of vaccines on the schedule). Given that, you should be able to eliminate some of the reasons you suspect and be able to narrow it down. Any chance you can do that? Or do you just have a religious faith that it is anything but the vaccines, (the same as we see with the current excess deaths being anything but the covid vaccines).

Doing a cross-continental medical comparison and blaming only one factor, among many, many others, that doesn't even differ very much does not remotely pass the sniff test for a study.

It's not religious faith, but you're going to need a lot more than a shoddy argument.

The argument, by the way, is so shoddy (by failing to be rigorous about both diagnosis methodology, and of differences in environment) that we could trivially use it to conclude that vaccines actually reduce incidences of autism, if we look at America as the undertreated high-autism, under-vaccinated baseline, and at Europe as the properly treated gold-standard... But I don't think that's what you're interested in exploring, no?

There may be a reason why this question attracts so many frauds, quacks, and fools. I postulate: the people who run well-made studies, that we can actually draw meaningful conclusions from aren't finding the answers that the frauds, quacks and fools like.
