אני בכלל לא נכנס פה למושג של טענות אמיתיות או נכונות, זה לא רלוונטי, אני אנסה לפרט, למרות שזה קשה לי, ככל שאני מתעמק בנושא יותר, אני מגיע למסקנה שאנחנו משוללי בחירה חופשים, שהכל הוא מעין אשליה שיוצרת אצלינו מן הרגשת סוכנות מזוייפת.
ישנם מחקרים, חלקם חדשים יותר, אשר הראו י ע"י שימוש ,FMRI, שההחלטה מתקבלת במוח חלקיקי שניה לפני שהיא מגיע לחלק המודע שלנו במוח, המודעות, מה שמוביל למסקנה שההחלטה מתקבלת עוד לפני המודעות אליה ברמה הנוירולוגית.
more recent studies have used
fMRI,
[6] single-neuron recordings,
[15] and other measures
[18]. Researcher Itzhak Fried says that available studies do at least suggest that consciousness comes in a later stage of decision making than previously expected – challenging any versions of "free will" where intention occurs at the beginning of the human
decision process.

מתוך אחד המחקרים, אני מניח שזה רק שאלה של זמן שמבחינה טכנולוגית ניתן יהיה לצפות ב 100% כמעט את ההחלטה, כמובן שצריך לקחת בחשבון את כל משתני הסביבה:
The conscious decision to push the button was made about a second before the actual act, but the team discovered that a pattern of brain activity seemed to predict that decision by as many as seven seconds. Long before the subjects were even aware of making a choice, it seems, their brains had already decided.
As humans, we like to think that our decisions are under our conscious control — that we have free will. Philosophers have debated that concept for centuries, and now Haynes and other experimental neuroscientists are raising a new challenge. They argue that consciousness of a decision may be a mere biochemical afterthought, with no influence whatsoever on a person's actions. According to this logic, they say, free will is an illusion. "We feel we choose, but we don't," says Patrick Haggard, a neuroscientist at University College London.

Some researchers have literally gone deeper into the brain. One of those is Itzhak Fried, a neuroscientist and surgeon at the University of California, Los Angeles, and the Tel Aviv Medical Center in Israel. He studied individuals with electrodes implanted in their brains as part of a surgical procedure to treat epilepsy
4. Recording from single neurons in this way gives scientists a much more precise picture of brain activity than fMRI or EEG. Fried's experiments showed that there was activity in individual neurons of particular brain areas about a second and a half before the subject made a conscious decision to press a button. With about 700 milliseconds to go, the researchers could predict the timing of that decision with more than 80% accuracy. "At some point, things that are predetermined are admitted into consciousness," says Fried. The conscious will might be added on to a decision at a later stage, he suggests.
