The Fathers of Behavioral Economics
OverThinQ is built on the groundbreaking research of Daniel Kahneman and Amos Tversky, whose work forever changed how we understand human judgment and decision-making.
Daniel Kahneman
1934 — 2024
Daniel Kahneman was an Israeli-American psychologist and economist who was awarded the Nobel Memorial Prize in Economic Sciences in 2002 for his work on the psychology of judgment, decision-making, and behavioral economics — work he developed alongside Amos Tversky.
Born in Tel Aviv in 1934, Kahneman grew up in Paris during the German occupation of France and survived the Holocaust. He later studied psychology at the Hebrew University of Jerusalem and earned his PhD from the University of California, Berkeley.
His bestselling book "Thinking, Fast and Slow" (2011) introduced millions of readers to the two systems of thought — the fast, intuitive System 1 and the slow, deliberate System 2 — that shape every decision we make.
Kahneman spent most of his academic career at Princeton University. He passed away in March 2024 at the age of 90, leaving behind a legacy that transformed psychology, economics, medicine, law, and public policy.
"Nothing in life is as important as you think it is, while you are thinking about it."
— Daniel Kahneman
Key Contributions
Amos Tversky
1937 — 1996
Amos Nathan Tversky was an Israeli cognitive and mathematical psychologist, widely regarded as one of the greatest minds in the history of psychology. His collaboration with Daniel Kahneman produced some of the most influential research in social science.
Born in Haifa in 1937, Tversky served as a paratrooper in the Israel Defense Forces and was decorated for bravery. He studied psychology at the Hebrew University of Jerusalem and earned his PhD from the University of Michigan.
Tversky was known for his razor-sharp intellect and wit. His colleagues often said that the fastest way to measure a psychologist's intelligence was to see how quickly they realized Tversky was smarter than them. He was a mathematical genius who brought formal rigor to the study of human irrationality.
He spent most of his career at Stanford University. Tversky passed away in 1996 at the age of 59 from metastatic melanoma — six years before the Nobel Prize was awarded to Kahneman for their joint work (the prize is not given posthumously).
"It is sometimes easier to make the world a better place than to prove you have made the world a better place."
— Amos Tversky
Key Contributions
Kahneman and Tversky's collaboration began in 1969 at the Hebrew University of Jerusalem and would last until Tversky's death in 1996. Together, they published a series of papers that fundamentally reshaped how we understand human cognition and decision-making.
Their 1979 paper "Prospect Theory: An Analysis of Decision under Risk" became one of the most cited papers in all of economics. It showed that people don't evaluate outcomes in absolute terms — they evaluate them relative to a reference point, and they feel losses roughly twice as strongly as equivalent gains.
Their work dismantled the assumption of human rationality that had dominated economics for centuries, giving birth to the field of behavioral economics and earning Kahneman the Nobel Prize in 2002. Kahneman always insisted the prize belonged equally to Tversky.
Michael Lewis chronicled their remarkable friendship and intellectual partnership in his 2016 book "The Undoing Project: A Friendship That Changed Our Minds".
These foundational concepts power OverThinQ's bias detection engine.
Anchoring Effect
People rely too heavily on the first piece of information they encounter when making decisions.
Availability Heuristic
Judging probability by how easily examples come to mind, rather than actual frequency.
Representativeness Heuristic
Assessing likelihood based on how much something resembles a typical case, ignoring base rates.
Loss Aversion
Losses loom larger than equivalent gains — losing $100 feels worse than gaining $100 feels good.
Framing Effect
Decisions change based on how options are presented, even when the underlying facts are identical.
Endowment Effect
People overvalue things they own compared to identical things they don't own.
Status Quo Bias
A preference for the current state of affairs, even when change would be objectively better.
Certainty Effect
Overweighting outcomes that are certain relative to outcomes that are merely probable.
Their Legacy Lives On
Every time OverThinQ detects a cognitive bias in your decision-making, it's applying insights that Kahneman and Tversky spent decades uncovering. Their work reminds us that understanding our mental shortcuts is the first step toward making better choices.
"The premise of this work is that the errors people make in judgment are systematic and predictable."
— Kahneman & Tversky, 1974
