IQ tests have always bothered me. They claim to measure ‘general intelligence’. I think this is bullshit.

The ‘productivity-pay gap’ has nothing to do with productivity. Here’s why.

For all that it purports to say, Gross Domestic Product (GDP) fails to explain anything relevant about the world.

Wages correlate with firms’ sales per worker. Does this mean that productivity explains wages? The answer is no.

Real GDP is key to macroeconomics. But is it a valid measure of economic scale?
