"Do you walk through the mysterious archway?"
"Do you drink the potion?"
"Do you push the big red button?"
If you're an old-school D&D player, you've probably got the necklace of strangulation and The Tomb of Horrors in the back of your mind. As such, the answer to all of the above is no doubt "hell no." My question is whether we, as GMs, should try to encourage daredevil behavior.
Yes, in general we should. Because if there was a catastrophic disaster involved in doing so, we would be complete dicks as GMs not to signal it. The Tomb of Horrors was designed specifically to break that rule; it is an exception to normal dungeon design.
If a GM has a big red button, with no way to get information on it, then if I push it I expect either something trivial, but probably fun to happen, or something with a mix of positive and negative consequences to happen. My first D&D game was a trap encounter like this: "You see a patch of flowers by the road"; "I sniff them"; "Save versus poison"; "12"; "you die". No-one nowadays thinks this is the way to design games.
