You may think you chose to read this, but Stanford scientist Robert Sapolsky would disagree. He says virtually all human behavior is beyond our conscious control.

This sounds like an interesting read.
If i may be so bold.
We all see the world through the pair of spectacles that we ourselves made through our learning and experiences.
And therefore we may be limited to see the world through that pair of spectacles.
I always found it interesting that polymaths because of the diverse interests and the broad knowledge, seem to have more than one pair of spectacles and seem to just swap one for the other as they seem fit. Sometimes just wearing them all at once.
We all know the saying to make children laugh and look at you awkwardly :
"
A person with a pair of spectacles on is smart. That is a rule in life.
Therefore if i wear multiple pair of spectacles at the same time, i am even more smarter...
"
In other words and my own humble opinion.
Freewill is initially a choice made on noise as input. And as we get older it is experience and noise. We choose constantly between experiences (fixed behavior) and we choose based on noise (random behavior).
Where noise is just noise or recombining data which only has loose similarities AKA turning on creativity. And we limit creativity by choice through boundaries to stay reasonable and sensible.
The chosen limitation prevents that we are being thrown into a psychiatric hospital pumped full with chemicals , where the doctors have no idea how the chemicals work but they make money of it.
Of course, this does not have to be our own experience. We also learn from the outside world... Another huge amount of (initially noise AKA chaos) variables.
if you want to know what is noise neurologically seen : Try sensory deprivation.
And avoid the drug experiments. Do not attack me, but anecdotal information seems to be that drugs to get smarter is the reason for memory segmentation in processor architectures long ago...
When artificial intelligence can do : "Eureka !" . It really works autonomously but we should also be scared of it...
