Please chime in with what you believe to be a "commonly believed myth", why you think people misinterpret them, and also why you believe it can't be true.
I'll start with everyone's favorite:
Myth: Targaryens are immune to fire.
This is frequently misinterpreted because of Dany's singular magical experience when walking into Drogo's funeral pyre. All indications show that this was a special case and does not indicate that she is fireproof. Dany herself is misinformed about the Targaryen relationship with fire, because when her own brother is killed by molten gold, she believes it is because he "was no true Dragon".
However, several other notable Targaryens erroneously believed the same thing, and yet died by fire. The fire at Summerhall killed Aegon, for example.
This myth is further propagated by the HBO show, and the HBO wiki even says "Targaryens have some common genetic traits such as silver-white hair. Some members of the family are also immune to the effects of fire, extreme heat, or high temperatures." source: http://gameofthrones...House_Targaryen
When Dany meets Drogon in the pit, she ducks to avoid his flame, so there is no indication that she was immune to it in that example.
Dany likes her water hot, but that also doesn't support immunity to fire.
