Why are our carefully planned cognitive biases suddenly forgetting their script on the landing page?

hey folks, remember that last thread about general psychological triggers? thought we finally cracked it. but now we're diving deeper into specific cognitive biases, and uh, things are getting weird again. it's like our software's gotten a mind of its own, refusing to play by the rules.

the problem is, we're trying to leverage some classic cognitive biases on our SaaS landing pages and pricing, but they're just not hitting. conversions are flat, sometimes even dipping. it's like our users have developed an immunity to all the usual tricks, or maybe they're just too smart for us, which is kinda rude.

we've tried a bunch of stuff:

• a/b testing various scarcity messages ("only 5 spots left," "offer ends soon"). we even tried "this page will self-destruct in 10 seconds" but that just made people close the tab.
• heavy social proof, including testimonials, live user counts, and "as seen on" badges. we even had our grandma write a testimonial, bless her heart.
• classic anchoring with our pricing, showing a much higher "original" price, then slashing it. it seems like people just look at the lower price and don't even register the "deal."
• framing our features with loss aversion in mind ("don't miss out on X," "avoid Y problem"). sometimes just spikes bounce rates, like they're running away from the problem we just highlighted.
• double checked our ui/ux to ensure it's not the culprit. everything looks clean, no broken buttons or anything.
• even dabbed a bit in light personalization attempts, like "welcome back, [user's name]!" but that feels more creepy then compelling.

but here's what's failing: scarcity often reduces clicks, making us wonder if it looks too pushy or just plain unbelievable. social proof seems invisible, like our testimonials are written in an alien language. anchoring doesn't make the actual price look better, it just makes the original price look ridiculous. and loss aversion? sometimes just spikes bounce rates. it really feels like our audience's consumer behavior is just... ignoring these fundamental psychological cues. are they too savvy for this? or is there a subtle mistake we're making that's completely flying over our heads?

so, really looking for anyone who's wrestled with similar resistance to cognitive biases in their marketing. any insights on why these tried-and-true techniques might be backfiring or just being completely ignored? are there specific audiences or product types where certain biases just don't land? what's the secret sauce we're totally missing here, before we resort to just showing cute cat videos on our landing page?

waiting for an expert reply.
