These kind of corrolation incidents are why the myth exists. The truth is that advertising companies like Facebook don't need to listen to us. They already know more than enough personal information about us to target ads.

Also explains why so many people think vaccines cause autism.

"I vaccinated my child and 6 months later he was diagnosed with autism. Cause and effect!"

Shame about your downvotes -- I guess people don't want to believe that vac. scepticism can be a reasonable conclusion from limited evidence.

Well: it is. Autism is a childhood disorder (therefore) whose symptoms usually follow vaccination. It is not unreasonable to hypothesize a causal link.

It may be unreasonable to maintain it in light of other evidence (eg., no difference in rate amongst the non-vax'd). But people don't live in the macro (ie., comparative contexts) they live in the micro (ie., their own experience). And its hard to communicate macros to micros.
