It's not the reason why this conspiracy got started. It got started by a fraudulent pseudoscientific paper with financial ties to it. We shouldn't be reducing human intelligence and ability to process information to the "wet streets cause rain" level. I know it's easier said than done though. When a scientist claims that "highly unlikely that vaccines cause autism", it still leaves the same room for doubt as when they say "it is very likely that vaccines do not cause autism".

The real issue isn't scientific caution. It's that the misinformation campaigns exploit any uncertainty, no matter how small. The solution isn't dumbing down science communication, but being clear about what the evidence actually shows.
