Glossary

• AgentAn agent is a person or thing that acts and makes choices. In discussions about free will, the agent is the one who is believed to have the power to originate their own actions. For example, in the sentence "The student chose to complete their homework," the student is the agent because they are the one performing the action and making the choice.
• ChoiceA choice is an act of selecting between two or more possibilities. It's the moment you decide what to do or think, and it's central to the idea of free will. For example, when you pick which elective class to take next year, you are making a choice.
• CompatibilismCompatibilism is the view that free will and determinism can both be true at the same time. It suggests that you can still make free choices even if those choices are part of a chain of cause and effect. For example, a compatibilist might say you freely chose to study for your exam, even if your desire to study was caused by your ambition and past experiences; you still acted on your own desires.
• ConsequenceA consequence is what happens as a result of an action or choice. Every choice you make, big or small, leads to certain outcomes or effects. For example, a consequence of choosing to stay up late playing video games might be feeling tired and unfocused in school the next day.
• DeterminismDeterminism is the belief that everything that happens, including all your choices, is already set in stone by things that happened before. It suggests that your actions are just the unavoidable result of past events and natural laws. For example, if you believe in determinism, you might think that your decision to eat pizza for dinner was actually decided by your genes, your past experiences, and even the weather, long before you even thought about it.
• Free WillFree will is the idea that you have the power to make your own choices and decisions, and that these choices are truly yours, not forced by anything else. It means you could have chosen differently. For example, choosing what to wear to school each morning, or deciding whether to study for a test or play a game, are everyday acts of free will.
• IncompatibilismIncompatibilism is the belief that free will and determinism cannot both be true; you must choose one or the other. If everything is determined, then you can't have free will, and vice versa. For example, an incompatibilist would argue that if your choice to cheat on a test was completely determined by your circumstances and brain chemistry, then you couldn't have truly chosen not to cheat, meaning you weren't free.
• IndeterminismIndeterminism is the idea that not everything is predetermined; some events, including human choices, are not completely caused by prior events. It suggests there's a real element of chance or genuine openness in the future. For example, if you believe in indeterminism, you might think that even if everything pointed to you choosing chocolate ice cream, you could genuinely and freely choose vanilla instead, without any prior cause forcing that choice.
• Moral ResponsibilityMoral responsibility is about whether you deserve praise or blame for your actions because you freely chose them. It's a special kind of responsibility tied to right and wrong. For example, if you freely choose to help a friend who is struggling, you are morally responsible for that kind act and deserve praise. If you choose to bully someone, you are morally responsible for that harmful act.
• ResponsibilityResponsibility means being accountable for your actions and their results. If you have free will, you are usually considered responsible for what you choose to do. For example, if you choose to break a rule, you are responsible for facing the consequences, like a detention or a talk with your parents.

Where this connects to other fields, and why it's worth knowing.

• Socialisation & the Self Sociology

  Your sense of right and wrong wasn't chosen by you; it was installed by whoever raised you, like software you never picked. So when we blame someone for a bad choice, we're partly blaming a program someone else wrote. That makes handing out blame a lot slipperier than it looks.

• How Habits Form and Break Psychology

  Addiction physically takes over the reward wiring your brain uses to make choices. If that machinery is hijacked, then relapsing looks less like being a bad person and more like a control system that's broken. That's unsettling, because it shakes up how we decide who deserves blame or punishment.

• Leadership and Decision-Making Business

  Imagine two CEOs make the exact same smart bet. One gets lucky and we call her a genius; the other hits bad luck and we call him a fool. We're really grading how the dice landed, not the choice they made. Judging leaders by outcomes secretly rewards luck and disguises it as skill.

• Criminal Law & Punishment Law

  Our whole system of blame and prison assumes you freely chose to do the crime. But if your choices are just brain chemistry firing, causes you didn't pick, then does 'you decided' even hold up? That's why free will is silently on trial in every courtroom, underneath the actual case.

• Causal Inference & Experiments Mathematics

  Saying 'X caused Y' secretly claims that in some other world where X didn't happen, Y wouldn't have either. That imaginary 'other world' is also how we assign blame and praise: he could have chosen differently. So a deep question about free will is quietly baked into every statistics class about cause and effect.

• Quantum Physics Science

  Some people hope tiny quantum randomness deep in the brain is what gives us free will. But think about it: if your choices came from a random dice roll firing in your neurons, that makes you unpredictable, not free. Random isn't the same as in control. Physics doesn't hand your free will an escape route after all.

• Black Holes Science

  Einstein showed there's no single 'now' for everyone; what counts as this instant depends on how you're moving. That hints the future is already laid out, just as real as the past. Which makes you wonder: if it's already there, do your choices really change anything?

• Chaos Theory & the Butterfly Effect Mathematics

  Some systems follow strict rules yet stay impossible to predict, because a tiny nudge blows up into huge differences. So 'everything is determined' doesn't mean 'everything is foreseeable.' That gap quietly shakes up the whole argument about whether we're free.

• AI in Medicine Health

  An AI and a doctor disagree, the AI's advice is followed, and the patient dies. Who's to blame? The AI has no intentions, just numbers crunched from old data. We don't even have the words to put a statistics program on trial.

• AI Governance Global Risks

  To blame someone, we usually need a person who could have chosen differently. But when a complex AI with no single author causes harm, there's no clear "someone" to point at. That old philosophy puzzle about free will suddenly becomes a real courtroom question: who pays?

• AI Safety & Alignment Technology

  NIST’s AI framework assigns importance to accountability and the roles of developers and deployers. This connects automated decisions to philosophical questions about agency and responsibility: who selected the system, authorised its use and could intervene? Allocating human responsibility does not require deciding that the model has free will.
