There definitely is some kind of unconscious decision-making. Consider also the times you're driving and arrive at your destination and don't remember consciously choosing to take the turns you did. Also relevant I think is ideas like flow and muscle memory, these spaces where you become so good at doing a thing or so used to doing the thing that you can do it at some unconscious or subconscious level.

But I think these unconscious decision-making spaces are evidence against the theory at OP's link, because they show we can tell the difference between conscious decision-making and unconscious decision-making. We have an established concept of mindless vs mindful action, and conscious minds can tell the difference on reflection.

There was a discussion in a meditation class I took recently, on the difference between an ethics class discussing the trolley problem in a sterile, classroom manner, vs when you're out in the world living your life, if you see an infant being washed away, drowning in a river, you may instinctually be driven to dive in, risking your own life without thought.

That is, there is a level you exist on where you know the right thing to do, but it's not even you, and not even knowing, there is just a happening occuring, and there is a right way to behave in the same way that there's a right way to behave for a ball rolling down a hill with gravity, or how there's a right way for molecules to complex based on the physics of their chemistry, there are also innate patterns at the body level for living well, like loving children and respecting elders.

The myriad techniques of meditation, then, exist as practices to align yourself with that natural flux of being. There are states of consciousness you can reach (states in the same way you can be awake, asleep, dreaming, ecstatic, furious, present, etc) in which you flow with that current of Being in the same way a rock on a hill flows with gravity.

At a certain state, experientially, you don't feel like you're meditating, the sensation is of being meditated. You aren't lost in your thoughts, your body is just flowing through the motions of being part of an integrated system in the biosphere, the same way your cells do their jobs and your organs do their jobs, so to are there roles you carry out in your position as a member of a family unit and community, and all of that can be incredibly easeful, if living in alignment with your Self and values

That would explain procrastination. Your consciousness wants to do something but the real shot caller is like "nah" or they can't even communicate at all.
