I can answer that quite easily.

I had a long held belief that Hitler escaped to South America. This belief BTW isn't that not that uncommon. This is because many other Nazis escaped to South America (including Martin Bormann) and it is perpetuated by Slop rubbish like "Hunting Hitler" TV series, stories about Hotel Bariloche etc.

The reason I no longer believe it is because I was ready to unbelieve it. I was no longer personally invested in it. I was personally invested in it because I believed it was "secret knowledge".

I finally accepted that it did not happen when I watched Mark Felton on Youtube do a 6 part series talking about the soviet investigation into Hitler's death. If I had watched that series several years earlier I wouldn't have accepted the facts contained within it.
