Bored with PhD - should I tell my supervisor?
I would think that framing it as &quot;being bored&quot; isn't going to be helpful, even if it is true. But you can certainly have a new conversation, suggesting that you think you would make more progress with a different strategy.
And burn-out is pretty common at your stage of things, so maybe it is that. I don't know whether telling the PI that you are starting to feel burned out and need something to refresh you would be helpful or not, but likely better than &quot;bored&quot;. But it is a question of knowing the supervisor well enough to judge their likely reaction.
And be sure to telegraph that you aren't at the point of quitting.
