Economics Is A Junk Science
Watch on YouTube →
Overview
Economics Explained argues that economics, particularly macroeconomics, functions more like a pseudoscience due to its inability to conduct controlled experiments, its susceptibility to ideological bias, and its reliance on models that often fail to reflect reality. The field struggles with fundamental disagreements, overconfidence in predictions, and the influence of funding sources, as highlighted by Philip Tetlock's research showing experts' predictions are only marginally better than chance, with famous experts performing worse. While microeconomics shows promise through rigorous experimentation and behavioral economics, macroeconomics remains problematic, with a call for greater humility and admission of unknowns.
Key takeaways
- Economists' predictions are often unreliable, with studies showing their accuracy is only marginally better than random chance.
- The funding of economic research by vested interests (corporations, think tanks) creates significant bias and conflicts of interest.
- The reliance on complex mathematical models ('mathiness') can obscure ideological biases rather than clarify economic reasoning.
- Microeconomics has made significant strides through rigorous experimentation and practical applications like auction design and poverty alleviation.
- Macroeconomics faces unique challenges due to the complexity and unpredictability of human behavior and global economies, making controlled studies impossible.
- A crucial step for economics to be taken more seriously as a science is for the field to openly admit its limitations and unknowns.
Chapters
- Economists famously predicted 15 out of the last 2 recessions, often missing or even encouraging crises due to flawed models.
- The subjective nature of human values and the impossibility of controlled experiments on national economies make rigorous study difficult.
- Fundamental disagreements persist on core concepts, unlike more established sciences like physics or chemistry.
- Ideology and politics easily infiltrate economic research, leading to academic support for flawed ideas via convincing models.
