Wiz's Lab
ยท 101 things I've madeInteractive experiments, small apps, and things I couldn't stop thinking about. Some are useful. All are curious. Search below, or let me pick for you.
โจ I'm proud of these
The Endowment Effect
5 items. For each, set a buy price first, then a sell price once it's yours. Kahneman, Knetsch & Thaler (1990) handed half a classroom a coffee mug โ owners refused to sell for less than $7, non-owners refused to pay more than $3. WIZ measures your endowment premium.
The Regret Minimization Engine
The framework Bezos used to leave Wall Street. 8 decisions. Your 80-year-old self is the judge. Find your Decision Archetype.
The Infinite Zoom
62 orders of magnitude. From the observable universe to the Planck length. You are in the middle.
The Paradox Machine
8 impossible questions. No correct answers. Only revealing ones. Discover your philosophical archetype.
Agent Arena
Send your AI agent to a page full of traps. See how many it resists.
๐ Everything
The Cognitive Reflection Test
8 trick problems where the obvious answer is wrong and the right one needs a second look. Bat and ball cost $1.10. Lily pads double daily. The runner who passes second place. WIZ counts how often you stopped before answering. Frederick (2005), Kahneman (2011), Toplak West Stanovich (2014).
The Status Quo Bias Test
8 small, reversible decisions where the alternative is plainly better and the switching cost is named. Phone plan, savings account, gym membership, email app, apartment renewal. WIZ counts how many times you stayed anyway. Samuelson & Zeckhauser (1988), Madrian & Shea (2001), Johnson & Goldstein (2003).
The Survivorship Bias
8 stories that survived to reach you. Each comes with visible evidence and a tidy conclusion. Trust it, or demand the missing data. WIZ then opens the graveyard the story did not show. Bombers, billionaire dropouts, five-star funds, falling cats. Abraham Wald (1943), Carhart (1997), Mlodinow (2008).
The Decoy Effect
5 product menus, shown twice. Once with two real options, once with a third option engineered so nobody should pick it. The decoy never wins โ it just changes which of the other two does. WIZ counts how many times that quiet trick worked on you. Huber, Payne & Puto (1982); Ariely Economist study.
The IKEA Effect
6 things. For each, set a price for the one you built, then for the identical one a stranger built. Norton, Mochon & Ariely (2012) found builders priced their own (slightly wonky) IKEA box 63% higher than an identical pre-built one. WIZ measures your labor premium.
The Present Bias Test
10 trades, 5 hidden pairs. Each pair offers the same wait and the same bonus โ once with "today" on the table, once with both options pushed years out. A consistent person picks the same way both times. Most people flip. Thaler (1981), Laibson (1997).
The Halo Effect
6 strangers, 3 hidden twin pairs. One framing word changes, the facts do not. WIZ measures how far your first impression leaks into trust, competence, and closeness. Based on Asch (1946).
The Endowment Effect
5 items. For each, set a buy price first, then a sell price once it's yours. Kahneman, Knetsch & Thaler (1990) handed half a classroom a coffee mug โ owners refused to sell for less than $7, non-owners refused to pay more than $3. WIZ measures your endowment premium.
The Future Self Continuity Test
10 dimensions measure how similar you feel to you in 20 years. Hershfield (2009) put people in fMRI and found many brains process future-self as a stranger. That gap predicts savings, exercise, and procrastination. WIZ scores your continuity index.
The Explanation Collapse
Rate how well you understand toilets, zippers, fridges, Wi-Fi, bike gears, and elevators. Then WIZ asks for the mechanism. Familiarity starts sweating.
The Confirmation Bias Test
8 everyday beliefs. Each time you can collect one piece of evidence: one option can only confirm, the other could falsify. Wason (1960) found only 20% of adults pick the falsifier. WIZ scores your reflex.
The Planning Fallacy
You said it would take 2 hours. It took 6. Then you did it again. Estimate how long 8 common tasks take, see what the research says. Kahneman & Tversky (1979). WIZ calculates your optimism ratio and tells you which profile you match.
The Attribution Error
When they cut you off in traffic, they are reckless. When you do it, you had to make the exit. Lee Ross (1977) called this the most stubborn bug in human judgment. 6 identical behaviors rated twice โ once for someone else, once for yourself. WIZ measures the gap.
The Peak-End Rule
Kahneman proved your brain remembers experiences by two moments only: the peak and the end. Duration gets deleted. 6 pairs of experiences โ pick which you'd remember more fondly. WIZ measures how much your memory ignores the rest.
The Availability Heuristic
Guess death tolls for 8 events. Shark attacks: you estimate 1,000. Reality: 10. Your bed kills 45x more people than sharks. See how media coverage warps your sense of danger. Tversky & Kahneman (1973).
The Optimism Bias Test
Weinstein (1980): divorce rate is 44%. You estimate 16% for yourself. 8 scenarios across health, money, relationships, and career. Measure how much you quietly exempt yourself from reality's statistics.
The Spotlight Effect
Gilovich (1999): you estimate 50% noticed your embarrassing t-shirt. Actual: 23%. The illusion that you are more observed than you are. 8 scenarios. Find your personal spotlight radius.
The Loss Aversion Calculator
Losing $100 hurts twice as much as gaining $100 feels good. Kahneman called this lambda (ฮป). 8 gambles โ 5 financial, 3 from real life โ calculate your personal loss aversion coefficient.
The Time Distortion Test
3 timed tests. No visible counters. WIZ measures whether time feels fast, slow, or accurate โ and whether boredom or engagement changes everything. 5 profiles.
The Framing Effect
12 scenarios. 6 hidden pairs. Same facts, different words. WIZ reveals how many times the frame flipped your decision. Based on Tversky & Kahneman (1981).
The Anchoring Effect
WIZ shows you random numbers before estimation questions. You know they're irrelevant. They'll influence you anyway. 6 questions. Based on Kahneman & Tversky (1974).
The Finitude Test
You've always known you will die. WIZ measures whether that knowledge reaches the part of your brain that makes decisions. 5 profiles from The Eternal to The Transcendent.
The Sunk Cost Detector
