Any monkey can fly straight-ish in IMC, with a little bit of radio chatter.
It's that exact misplaced belief which leads a number of victims to their deaths, every year. Controlled flight into terrain, inadvertant entry into instrument conditions, continues to be one of the leading killers in private flying, right after fuel mismanagement/exhaustion.
A big segment of situational awareness is recognizing these myths and internalizing the concept that they are not true. Anything else is just fooling yourself.
