Overlooked rarely shows up as just one thing. Not getting credit for work that was actually yours. Getting passed over for a promotion that made sense on paper. Struggling to get heard in a meeting when you had the better answer. Most writing treats these as separate problems, one piece about credit, another about promotions, another about meetings. In practice they're rarely separate. A specific, recognisable cause usually sits underneath more than one of them at once. Workplace psychology backs that up, this isn't random, it follows a pattern. And a pattern is something you can learn to work with, not just something that happens to you.
What's below is organised by what each situation is actually about, not by how it shows up on the surface. Each one is a different shape that cause tends to take, in meetings, in who gets the credit, in who trusts you with what, in whether there's an actual path ahead. You don't need the exact story worked out yet. Pick whichever one matches what you're actually trying to do, understand what's going on, or start doing something about it, and read from there. If you already know precisely what you're dealing with, search the full list instead.
