  • Hang on a second. It makes perfect sense (to me anyway) that if we were told that, in the near future, we were going to have to make a decision that our brain would subconsciously prepare for that decision. Wouldn't a more accurate experiment involve a test subject that was unaware of the choice they are going to have to make?? I'm probably missing the whole point here...

  • what would the data show if she had anticipated pushing the button and then changed her mind a split second before she was going to and decided not to push the button

    I believe he said 2000 milliseconds, which is two seconds. Also, turn off the caps lock, you sound like an idiot.

  • WE ARE TALKING ABOUT 200 MILI SECONDS HERE. ONE WOULD ASSUME THIS IS THE TIME TAKEN FOR YOUR BRAIN TO SND A SIGNAL THROUGH YOUR NERVIOUS SYSTEM AND INTO YOUR MUSCLE TISSUE TO PRESS THE KEY ON THE KEYBOARD AND SEND AN ELECTRIC IMPULSE THROUGH ALL THE COMPUTER CHIPS. iF THIS ISNT THE CASE THEN THIS VIDEO DOSENT REALLY EXPLAIN THE CONCEPT IN A CONVINSING WAY :-)

  • Surely, there should be much more variations of the experiments conducted to decide. This experiment alone cannot decide anything.

  • The experiment does not indicate if there were any false positives. Did brain activity build up when she did not press the button?

  • How do we make this argument against freewill based on this experiment without resorting to the post hoc ergo propter hoc fallacy?

  • Just because there was brain activity doesnt mean she doesnt have free will

  • I came to this video via the novel "How to Live Safely in a Science Fictional Universe"...

  • @xXfsasXx What you described sounds to me like an experiment to see if our brains can start preparing a decision for a situation the brain doesn't have any information about yet? I think that would be an experiment trying to find if our brains can predict the future
