I picked "brave," but only because there wasn't a "stupid" category to choose from.
Even when I'm home alone and I hear a strange noise, it doesn't even occur to me that what I've heard could potentially be something (or someone) dangerous. I just get up and go investigate. Fortunately for me, it's almost always one of the cats doing something crazy.
Good luck breaking into my house late at night, though. It's dark and your eyes will be dazzled from the streetlights and the security light, there are cat toys and cat trees scattered across the hallway floor, everything valuable is shut in the living room behind a door barricaded with a large cat tree (to prevent the cats from pulling the french door open), and if you don't trip over a toy or a cat, you've got myself and my (rather tall and muscular) FI to contend with. And we have swords.
