Question 1 of 6
Why does the author use the anecdote about the world balancing on a series of turtles?
  • A. To demonstrate that ancient philosophical theories often hold the key to modern neuroscientific discoveries.
  • B. To argue that just as an infinite tower of turtles is absurd, so is the idea that biological determinism suddenly stops to allow for free will.
  • C. To illustrate how the human brain relies on foundational childhood memories to make complex decisions.
  • D. To show that human evolution is a slow, methodical process that builds upon previous generations.
Question 2 of 6
What did neuroscientist Benjamin Libet's experiments reveal about human decision-making?
  • A. The brain initiates action roughly 200 milliseconds before a person is consciously aware of making a decision.
  • B. Conscious decisions are made in the frontal cortex, while unconscious reflexes bypass the brain entirely.
  • C. Humans have complete 'free will' only when making decisions that do not involve immediate physical danger.
  • D. The brain requires at least two full seconds of conscious thought to override a biological impulse.
Question 3 of 6
According to the text, what is the concept of 'free won't'?
  • A. The inability of the brain to process complex moral decisions under extreme stress.
  • B. A legal defense used to argue that a person was biologically predisposed to commit a crime.
  • C. The brief window of time where a person can consciously veto an action that their unconscious mind has already initiated.
  • D. The psychological phenomenon where individuals refuse to accept that their actions are predetermined.
Question 4 of 6
How does the development of the frontal cortex relate to the book's argument against free will?
  • A. It is fully formed in utero, making our baseline morality completely dependent on our genetic code.
  • B. It dictates immediate sensory responses, such as sight and hearing, which are hardwired from birth.
  • C. It is the only part of the brain that remains completely immune to the effects of chronic stress and trauma.
  • D. It forms primarily during adolescence, meaning our executive function is heavily shaped by environmental factors rather than just genes.
Question 5 of 6
According to the text, how do immediate physical states and sensory inputs affect split-second decisions?
  • A. Professional training completely overrides a person's biological impulses during high-stress situations.
  • B. Biological markers like hunger, foul smells, and testosterone levels actively alter our judgments and prejudices in the moment.
  • C. The brain temporarily shuts down the frontal cortex when making split-second decisions to rely purely on genetic coding.
  • D. Only long-term childhood trauma affects our split-second decision-making; immediate physical states are irrelevant.
Question 6 of 6
If society accepts that free will does not exist, how does the author suggest we handle dangerous individuals?
  • A. Society should eliminate all laws and allow biological determinism to naturally regulate human behavior.
  • B. Criminals should be punished more harshly to create a strong environmental deterrent against future crimes.
  • C. The justice system should focus on removing dangerous individuals from society to keep people safe, without inflicting moral punishment.
  • D. Only individuals with identifiable genetic mutations should be exempt from the traditional punitive penal system.

Determined — Full Chapter Overview

Determined Summary & Overview

Determined (2023) argues that free will is an illusion – all human behavior stems from biological and cultural factors we don't control. Through scientific research and case studies, it lays out the argument in favor of determinism, and aims to persuade why rejecting the notion of free will might be a positive step.

Who Should Listen to Determined?

  • Philosophers interested in free will, determinism, and human agency
  • Neuroscientists and psychologists studying decision-making
  • Anyone curious about what guides human behavior and choices
