Fantasyland. The truth is never "extravagant." If anything needs readjustment, it is our own prejudice. I've seen it too many times: "In order to overcome my prejudice, you need to provide extra-special proof...and I get to decide what constitutes proof." No. When the evidence is at par with the previous consensus, then both must be put on the table. Past belief doesn't count. (Remember phlogiston?)
