Remembrance - S1-E1
Stupidity: In this episode wily old battle genius Jean-Luc Picard and amazingly smart human-android Dahj act exactly by the definition of stupidity of this website ("something daft, like running upstairs with a killer behind them, instead of out of the front door"), and even surpass it, because the killers are not even chasing them yet. And why not? Because they are in a public area with a ton of people in the middle of what is basically the capital of the world; no band of kidnappers would attack at that point, or at least, it's way more unlikely. But from there, our nearly centenarian hero (steps away from official government buildings and in a world with communicators, teleports etc.) goes up a ramp of stairs leading to a desert rooftop with no exit and no witnesses, exactly where a group of evildoers would attack - and are even able to cover their tracks up exactly because of this choice.
