I saw a video about a fatal oil drilling accident where the resulting investigation found that an operator had ignored the alarm which indicated the underlying issue because there were other alarms sounding for things he'd been told to ignore because they were benign. This is apparently common enough cause of problems that there is a term for it (other than "crying wolf"): https://en.wikipedia.org/wiki/Alarm_fatigue
I've seen it during my career as a software developer, too. Heaps of alert spam that remained unread because 99% of them were useless and not indicative of a problem on our end. It's important to be careful about alerts so you know when real problems occur.
This also how a part of how a certain flagship got promoted to a submarine recently.
In France, we have a bed story for children related to exactly that: "Pierre et le loup" (aka your "crying wolf").
It may be a EU wide tale.
On a finance level this is why correctly setting 'accidental trade limits' correctly is important. Otherwise traders see them so often they click through them.
And because of this, no browser of mine is allowed to send notifications, and also no app by default - they have to prove themselves useful first. Sorry fellow developers working on notifications, your work goes to the drain (mostly).
In the US spewing all the alarms at the line level employees and fatiguing the shit out of them is a direct (and predictable, but of course everyone who complained in advance got sneered at by the usual demographics) result of OSHA policy. Same bunch of moronic incentives that result in there being a policy against everything and employees technically violating the rules to work normally. Whenever you see an alarm fatigue workplace there's usually a rule in the rulebook that says they have to stop what they're doing for every alarm until it's triaged and documented. This is how the rules financially incentivize the company to act even if it's stupid and results in more screw ups.
Reminds me of my time in a large dormitory. The first time the fire alarm went off at night without there even being a fire, I went outside. All the other times - and I lost track of counting - I just ignored it and went back to sleep.
