    Study Notes

    Parkinson's Disease and Gambling

    • L-dopa, a treatment for Parkinson's disease, can lead to compulsive gambling in some patients.
    • This may be because L-dopa increases dopamine levels in the brain.
    • Dopamine is a neurotransmitter associated with reward and pleasure.

    The Narrative Fallacy

    • We have a tendency to impose meaning and patterns on random events.
    • This tendency is related to how our brains store and retrieve information.
    • The left hemisphere of the brain is responsible for interpreting events and constructing narratives.
    • Our brains are wired to seek patterns, even when they don't exist.
    • This can lead to overconfidence in our ability to predict the future.

    Dopamine and Pattern Perception

    • Dopamine plays a role in our tendency to perceive patterns.
    • Higher dopamine levels are associated with increased pattern perception and reduced skepticism.
    • This can make people more susceptible to fads and superstitions.

    Black Swan Events

    • Black Swan events are rare, unpredictable, and have significant impact.
    • We tend to underestimate the possibility of Black Swan events.
    • This is partly because we are not naturally programmed to account for them.
    • We often focus on familiar patterns and fail to consider the possibility of novel events.
    • We tend to overestimate the likelihood of familiar Black Swan events and underestimate the likelihood of unfamiliar ones.
    • This can lead to decision-making biases and a failure to prepare for unexpected events.

    Risk Taking and Black Swan Events

    • Stability and absence of crises can lead to increased risk taking.
    • This can lead to a false sense of security and an underestimation of potential risks.
    • We tend to worry about the wrong improbable events, often overlooking the true threats.

    The Distortion of Silent Evidence

    • Black Swan events are often hidden from us by history.
    • We tend to rely on past experiences to predict the future.
    • This can lead to an inaccurate assessment of probabilities.

    Consequences of Black Swan Blindness

    • We can overreact to predictable risks while neglecting unpredictable ones.
    • This can lead to poor decision-making and a vulnerability to unexpected shocks.
