When it is so well known, at some point it isn’t a “trick” anymore, right?

It isn’t as if retailers can fight reality.

Or that they can “come clean” by putting fine print under prices explaining why they are ending prices in 9. Which would create a major distraction messing with any sale.

It is just real-world reliable wackiness that both sellers and purchasers should be aware of.

There is no purely objective way to relate to selling and purchasing prices. Short of very simple scenarios where a spreadsheet actually captured all the real criteria.

Many products make people happier if the price is higher. Is that happiness bump a fraud, or the point?

Just remember to ask for $199,999.99 salary in your next interview!

Why would they do that? That might lessen their sales if people knew of the effect, as a nocebo.

I agree(d).

As you consider the issue this phrase I think is the best synopsis of your thoughts: When it is so well known, at some point it isn’t a “trick” anymore, right

And yet we fall for the same tricks again and again. The most politically pressing? The number of people - internationally - who believe in a strongman leader.

MLMs also occur to me. We know MLMs so well that we've literally written laws against them. There are movies, articles, conversations. And yet, every single year, tons of people fall for them.

What other very well-known tricks do people fall for HN?

FOMO (invite only), trial periods, and decoy pricing are a few tricks I've fallen for in the past. I try to be vigilant, but sometimes it's just too much.

That’s pretty ingenious to call people dumb. This is psychology and these tricks work on you even if you trivially understand that 3.99 is not feasibly cheaper than 4.00 — your brain simply processes information non-stop in the background and you are affected by this. Hell, there was even a study that people who claim they don’t fall for these kind of marketings tricks are more susceptible to fall for this, so, take what you want from it.

Also, even knowingly false propaganda has an effect on you.

Ingenious? Or disingenuous? Regardless, I agree with you, "tricks" and "dumb" was not said derogatorily, I meant basically what you said, that humans are biologically "dumb" in terms of falling for these "tricks," similarly to how optical illusions work. It seems you summarized my point better than I could.
