I wonder if you could publish the opposite result without your career being corporally punished.

Probably depends on how you came to the opposite conclusion; if peer-reviewed research showed that outcome, it'd probably be a lot easier than if it was just "I turned out fine."

I've read comments that sound just like yours from consparicists any time another study disproves links between vaccines and autism. You might consider whether the reason the opposite view isn't well-regarded is because it's disproven.
