Have a question about how the TVTropes wiki works? No one knows this community better than the people in it, so ask away! Ask the Tropers is the page you come to when you have a question burning in your brain and the support pages didn't help.
It's not for everything, though. For a list of all the resources for your questions, click here. You can also go to this Directory thread

This is really a question for the "Is this an example?" thread on the forum, but (being something of a self-appointed expert on this film since it's easily my favorite of the sequel trilogy)...
It's definitely not an example of Informed Wrongness. As you said, neither Poe nor anyone else had any way of knowing that the First Order could track them. Poe was demoted for disobeying a direct order from his de facto commander-in-chief (not merely a superior officer) and getting their entire bomber complement blown up for a (based on what was known at the time) operationally unnecessary objective, which meant that Holdo couldn't trust him to obey her own orders, either (not to mention that even if she gave him his CAG post back, there's no fighters left for him to be CAG of). And after he laid hands on her in the meeting room, Holdo would have been fully within her rights to throw him in the brig until further notice; her only mistake was trusting him to obey orders to sod off to quarters until she needed him to fly a transport off the Raddus.
It's also not an example of Moral Luck (which probably needs to be made NRLEP and In-Universe Examples Only): that describes a character being praised or condemned for things they had no control over. Poe disobeyed orders, therefore he had full control of the circumstances.

This was added to YMMV.The Last Jedi.
This has been heavily debated, more points for both sides raised than can be summed up here, and removed prior. My thoughts is it's misuse as that wasn't the reason Poe went through with the attack that might have had zero casualties if called off, and it was only due to hyperspace tracking that was unforeseeable and thought impossible that he was proven "right" through luck.
Maybe IW applies due to this being the same kind of poor planning/Hollywood Tactics that was normal and overlooked as bad for the series prior making Poe's condemnation for it seem unfair. It’s likely why this is so ongoingly contentious.
Might Moral Luck apply? My belief is that it only should apply in international/self-aware moments, but I've seen it used for unintentional examples as complaining redundant with Unintentionally Sympathetic/Unsympathetic. Cleanup argued against putting ML under the Writing Pitfall Index so use as a complaint/unintentional examples seem misuse.
