Neuroscience shows that a thought can be traced in the mind seconds before someone is aware of it. It is a reaction to a cause and you have absolutely no control over it, no free will.
It is certain. If you put certain chemicals together in an experiment they will always produce the same effects. Put the same cause and the same environment together and again, you will always act the same way
If you knew everything you could predict the future with 100% accuracy. If you replayed this day 1,000 times every choice made would be the same, as it has the same environment, the same causes and thus the same effects.
Well, that was the classical belief, but the modern understanding is that all characteristics of the natural world cannot be fully known at the same time. Spin off of Uncertainty.
If you put particular components into an experiment, you will always get the same result. Always. The world is just an incredible complex experiment, but nonetheless, you will always get the same result. What you put in is what you get out, every time.
Nope. With modern technology you cannot possibly control every variable in an experiment. Wether it is the final weight or the particular weight you can not consistently get the same exact results every time
I make a conscious decision on how to act. I actively decide to report bullying even if it makes me socially different. That goes against basic human nature of conformity. If an outcome was truly predetermined I would stand by and watch like everyone else. Therefore free will exists.
No, your predisposition was caused by things entirely out of your control. Thoughts come into your head from the subconscious, and are created seconds before you are even aware of them, beyond any choice you make.
Basic human nature would make that outcome impossible if everything was predetermined. Basic nature promotes conforming to other humans. The fact that I can act against my best interests shows free will.
