Circuit Breaker: Rewiring Your Decisions – Détails, épisodes et analyse

Why do people fail to step in during an emergency — even when they know someone needs help? In this episode of Circuit Breaker: Rewiring Your Decisions, we explore the psychology behind the bystander effect — the strange social phenomenon where the presence of others makes us less likely to take action. From classic studies by Darley and Latané to real-world moments where hesitation can have serious consequences, we uncover how responsibility gets diluted, how uncertainty freezes us, and how we take cues from those around us without even noticing.

Discover how to recognise the moments when you’re silently waiting for someone else to act — and how to break the paralysis so you can step forward when it matters most.

Why do we go along with the crowd, even when we know they might be wrong? In this episode of Circuit Breaker: Rewiring Your Decisions, we dive into the psychology of group conformity — the powerful social pull that makes us blend in, stay quiet, and follow others, often without realizing it. From classic experiments like Asch’s line test to everyday situations where peer pressure subtly shapes our choices, we uncover how group influence can override logic, independence, and even morality.

Discover how to spot when you’re conforming just to fit in — and how to break free from the herd when it matters most.

Why do ordinary people follow orders that go against their morals? In this episode of Circuit Breaker: Rewiring Your Decisions, we look at the psychology behind obedience to authority. Through the lens of Stanley Milgram’s shocking experiment, we explore how power, pressure, and perceived responsibility can override personal judgment.

Learn what this reveals about human nature—and how understanding it can help you make decisions that are truly your own.

Why do some people spiral into addiction while others — even with the same access — stay completely fine? In this episode of Circuit Breaker: Rewiring Your Decisions, we dive into Bruce Alexander’s groundbreaking work on addiction, namely, the famous Rat Park experiment. His research shows that addiction isn’t just about drugs — it’s about environment, connection, and purpose. Rats in isolated, barren cages became addicted, while those in enriched, social environments avoided drugs almost entirely.

Discover how social disconnection, loneliness, and lack of meaningful engagement can drive addictive behaviour — and how creating supportive, connected environments can help prevent or even reverse it. This episode will change how you think about addiction, shifting the focus from individual weakness to the power of context and human connection.

Why do subtle cues in our environment quietly shape our thoughts, feelings, and decisions—often without us noticing? In this episode of Circuit Breaker: Rewiring Your Decisions, we dive into priming — the psychological phenomenon where exposure to certain words, images, or ideas can influence how we interpret the world and how we behave next. From tiny triggers that nudge our mood to hidden cues that shift our judgement or performance, we uncover how effortlessly our minds can be steered in a particular direction.

Discover what priming reveals about the automatic mind, how everyday environments quietly “set the tone” for your choices, and how becoming aware of these subtle influences can help you take back control of your decisions before they’re made for you.

Why do ordinary people slip into cruel or submissive roles the moment power is handed out? In this episode of Circuit Breaker: Rewiring Your Decisions, we examine the Stanford Prison Experiment — the infamous study that revealed just how quickly authority, environment, and assigned roles can transform behaviour. From guards who escalated into aggression to prisoners who internalised obedience and distress, we explore how the situation—not personality—can push people into extremes they never imagined.

Discover what this experiment teaches us about the power of context, how easily we can lose ourselves in the roles we’re given, and how to stay grounded when a situation starts shaping you more than you realise.

Why do rare events feel far more common than they really are? In this episode of Circuit Breaker: Rewiring Your Decisions, we explore the availability error — the mental shortcut that makes us judge probability based on how easily examples come to mind. From dramatic news stories to personal memories that stick with us, we uncover how vivid or recent information can distort our perception of risk, influence our decisions, and quietly shape our fears and beliefs.

Discover how to spot when your judgement is being guided by what’s most memorable — not what’s most accurate — and how to recalibrate your thinking when it matters most.

Why do unfinished tasks stick in our minds long after we've stopped working on them? In this episode of Circuit Breaker: Rewiring Your Decisions, we explore the Zeigarnik Effect - the psychological phenomenon where incomplete tasks are remembered more clearly than completed ones.

Discover why open loops create mental tension, how unfinished work captures your attention, and how to use this effect to stay motivated.

Why does losing something hurt more than gaining the same thing feels good? In this episode of Circuit Breaker: Rewiring Your Decisions, we explore loss aversion - the psychological bias that makes losses feel more powerful, painful and important than equivalent gains.

Discover how fear of loss shapes decision-making and behaviour; why we cling onto what we already have; and how to overcome this bias to get rid of old ideals and create space for improvement.

Why do we choose short-term rewards even when we know waiting would be better? In this episode of Circuit Breaker: Rewiring Your Decisions, we explore temporal discounting - the tendency to value immediate rewards more highly than future ones, even when the future payoff is larger or wiser.

Discover how time distorts our judgement, and how understanding this bias can help you make decisions that you future self will actually thank you for.
