I would rather be misinformed
If I had to choose between being uninformed or misinformed, I can honestly say I'd rather be misinformed. I know, I know, there are definitely some disadvantages to being misinformed, the most obvious one being it's because someone lied to you.
Discovering this lie could hurt and make you question the person, may even make you think that you did something wrong, but I'd still say that's better than being uninformed. Imagine you hear that your friend is having a party but it was canceled, only to later learn that it wasn't actually canceled, they just didn't want you there.
Now first off, I'd say it's probably time to question how much the person values that friendship, but looking past that, in this scenario you've been lied to. While some may say they prefer not to have known about the party in the first place, I'd prefer to have known and been lied to. This is for one simple reason.
If you've been lied to, that means the person felt the need to come up with an excuse to give you, that they thought about you and considered you when making their plan. It means that at least some part of them will be aware of the fact that they lied while they're enjoying their party, at least some part of them will feel guilty about what they've done.
On the other hand, if the person had not even told you about the party, then that means they didn't even feel the need to consider you, it as though you are a fly, sitting on the wall, staring in at their life, but something that they would swat away if given the chance.
I won't lie, being misinformed would still suck. But being uninformed is worse because while you may not be aware of what's happening, that doesn't change reality. And chances are, at least in scenarios like this, either way, you'll be hurt. But I'd at least want some information than to not be thought of at all.
