cognitive biases killing conversions?

man, i'm seriously losing my mind here. we've been trying everything from the last discussion about psychological triggers – scarcity timers, social proof with testimonials everywhere, even some mild anchoring. conversions are flatlining, absolutely nothing is moving the needle. it's like our users are immune to all of it. i thought i had a good handle on some basic cognitive biases but this is just not working out. we're pouring resources into these tactics and it's just... dead.

i'm starting to think it's not the triggers themselves but maybe how we're applying them or something even deeper about our specific audience's user behavior. how do you even begin to diagnose *why* these well-known psychological tactics are failing? is there some kind of framework or a step-by-step process to understand user decision-making better when the obvious stuff isn't landing? i'm desperate for some new angles here. help a brother out please...
