Rationality: Awareness
Understand what rationality means, what's possible, and where you stand. About 15 minutes.
The quality of your thinking shapes nearly every outcome in your life. Career choices, financial decisions, relationships, health habits – all of these depend on how well you reason under uncertainty, how accurately you model the world, and how reliably you can identify the best course of action.
Most people overestimate the accuracy of their beliefs and the quality of their decisions. Research on calibration consistently shows that people's confidence in their judgements tends to exceed their actual accuracy. This gap between perceived and real reasoning ability is one of the most robust findings in psychology.
The good news is that reasoning skills are trainable. Studies from the Good Judgment Project found that relatively brief training in probabilistic thinking and bias recognition improved forecasting accuracy by around 30%. Participants who practised structured reasoning outperformed professional intelligence analysts with access to classified information.
Rationality also serves as a multiplier for other life areas. Better reasoning about nutrition evidence helps you eat well. Clearer thinking about financial risk helps you invest wisely. More accurate models of other people help you build stronger relationships. Few skills compound across as many domains.
People develop their thinking for different reasons. This site scores every rationality intervention across three core values. Later, you'll set your own weighting across these three values, and the site will rank interventions by how well they deliver on the things you actually care about.
Accurate Beliefs
Developing more accurate beliefs about how the world actually works. Better calibration (your confidence matching actual accuracy), making more accurate forecasts and predictions, updating appropriately when presented with new evidence, and building superior mental models and heuristics for navigating complexity. People who lean towards this value focus on the outcomes of thinking – actually having true beliefs and understanding reality correctly, even when the truth is inconvenient or uncomfortable.
Effective Decision-Making
Using clear thinking to achieve your actual goals across all life domains. Avoiding costly mistakes from cognitive biases, developing systematic approaches to complex choices, improving your track record of successful outcomes, and building effective models and heuristics for practical decision-making. People who lean towards this value see rationality as a practical toolkit for getting what they want more reliably and avoiding expensive errors in judgement.
Intellectual Honesty
Maintaining truthful reasoning processes and admitting uncertainty appropriately. Changing your mind when evidence warrants it, acknowledging the limits of your knowledge, following arguments where they lead even when conclusions are personally uncomfortable, and recognising when your reasoning is motivated by comfort rather than truth. People who lean towards this value focus on the process of thinking – maintaining genuine truth-seeking as important in itself, regardless of whether it leads to immediately better outcomes.
The Top 0.1% band represents roughly 1 in 1,000 people. To give you a sense of what that looks like for each rationality value:
The top superforecasters from the Good Judgment Project consistently outperformed professional intelligence analysts by 30% or more, despite having no access to classified information. These individuals – ordinary people with no special credentials – achieved this through disciplined calibration, granular probability estimates, and systematic belief updating. Over four years of geopolitical forecasting tournaments funded by IARPA, the best of them maintained Brier scores that placed them in the top fraction of a percent of all participants.
Annie Duke was one of the top female poker players in history, winning a World Series of Poker bracelet and over $4 million in tournament earnings. She later applied the same structured decision-making frameworks – expected value calculations, separating decision quality from outcome quality, pre-mortems – to advising organisations and writing on decision science. Her track record spans thousands of high-stakes decisions under genuine uncertainty, with verifiable outcomes.
Douglas Hofstadter has spent decades publicly grappling with questions about consciousness, cognition, and artificial intelligence, consistently revising his positions as evidence and arguments demanded. Despite his strong initial scepticism about AI systems replicating aspects of human thought, he has openly acknowledged being shaken by recent developments and has discussed the discomfort of confronting evidence that challenges his life's work. This willingness to sit with uncertainty on questions central to his identity is unusual among prominent intellectuals.
Awareness means knowing your starting point. Answer each question below – some you might know off the top of your head, others might take a few minutes to reflect on.

Your estimated position
Percentiles are estimates based on published data on calibration practices, decision-making habits, cognitive bias awareness, and intellectual humility research. All items in this area are scored.
You now understand why rationality matters, what different people get out of it, what's achievable, and where you currently stand. The final step is to set your personal value weightings and see which interventions are the best fit for you.
On the interventions page, adjust the sliders to reflect how much you care about accurate beliefs, effective decision-making, and intellectual honesty. The table will re-rank interventions to match your priorities.
