Catch your mind in the act.
Behavioral economics and cognitive psychology tools to detect the biases running quietly in the background — then resist manipulation, break automatic loops, and build better habits. Built on Kahneman, Cialdini, Duhigg, and peer-reviewed behavioral research.
The mind runs on autopilot. Make it visible.
Each tool surfaces a hidden cognitive process — the bias, the habit loop, the manipulation tactic — and gives you a way to interrupt it.
The Cognitive Bias Detector
Describe any decision you're wrestling with, or paste an argument, ad, or email — and the detector surfaces the cognitive biases likely at play. Grounded in the Cognitive Bias Codex (180+ biases) and Kahneman's System 1 / System 2 framework. Returns the three most likely biases, their mechanism, and how to counter them.
Habit Architect
Design a habit that actually sticks — using the cue-routine-reward loop (Duhigg) and BJ Fogg's Tiny Habits method. Specify the behavior; the tool reverse-engineers the anchor, the environment, and the minimum viable version.
Sunk Cost Calculator
Am I staying because it's right — or because I've already put in too much? A structured walk-through that separates recoverable investment from sunk cost, and reframes the decision as if you were starting today.
Persuasion Scanner
Paste any ad, political message, or sales pitch — the scanner identifies Cialdini's six weapons of influence (reciprocity, scarcity, authority, commitment, liking, consensus) and the specific tactics being used on you.
Procrastination Diagnostic
Procrastination is rarely laziness — it's usually one of six underlying drivers (fear, ambiguity, perfectionism, lack of autonomy, task aversion, or unclear reward). The diagnostic identifies yours and matches it to the evidence-based intervention.
How Behavior Lab tools are built.
Three principles distinguish a real behavioral-science tool from a personality quiz with good typography.
Mechanism, not moralism
We don't tell you what's "good" or "bad" behavior. We surface the mechanism — why this pattern is running, what it's doing for you, what it's costing — and let you decide. Behavioral science describes; it doesn't prescribe.
Grounded in primary research
Every framework traces back to published research — Kahneman's Thinking, Fast and Slow; Cialdini's Influence; Duhigg's The Power of Habit; Fogg's Tiny Habits; Steel's meta-analysis on procrastination. Cited inline, not hidden.
Interrupt, don't judge
The goal of each tool is not to rank you against a normative ideal — it's to create a pause long enough to notice what your System 1 is already deciding. One moment of awareness is worth more than a lecture on willpower.
