I would say I think it's a combination, but I don't know.
I would give an example about raising from UTG. The logic is to raise from UTG with very good hands. So, if you think the UTG player has a really good hand, you're going to fold everything that isn't a very good hand. This makes his raise automatically profitable, because you're going to fold a lot (I don't know if it would really be profitable, it depends on the bet size too, but I think it would be).
So, by logic, you would lose money. But to counter that would be logic, not intuition.
I studied decision making in college and the difference between deliberate and intuitive decisions.
Intuitive decisions are more accurate in some ways because only the most fundamental information is considered to make a decision.
One study found that people better predicted NBA outcomes using intuitive decisions (vs. the group that had to come up with an explanation and predict the outcome), likely because they started thinking of less influential things in the outcome, or gave equal weight to different aspects. For example, when you look at the schedule and you see Knicks vs. Nets, you say Nets. If you start to analyze a lot, you can see that the Nets were playing in Los Angeles, so they might be tired, and you say, oh, I think the Knicks take this one. While this travel information is relevant, Kevin Durant carries more weight in determining the winner than the distance of the travel.
That said, I think you have to deliberate a lot, mainly because it will improve your intuition.
And there is a difference in the learning process. Explicit learning (reading things, watching videos, etc.) helps with deliberative decision making, and implicit learning (playing) further improves intuitive decision making. But implicit learning is not enough in more complex things (like poker). So you have to study (explicit learning) and play (implicit learning). And you will make deliberate and intuitive decisions. In the beginning you will deliberate a lot, make a lot of mistakes, but you will start to improve, understand things better and make more intuitive decisions. But intuitive decisions are not always better than deliberative decisions, so pay attention to this, so, with experience, you will understand at what points you should choose one or the other.
