Correlation vs Causation (Simple Explanation)

Why We Falsely Link Effects to Causes When two things happen together, it’s tempting to believe that one caused the other. For example, in the previous chapter, we saw that the economy improved while crime rates dropped. This seems like a satisfying explanation, until the data show the economy couldn’t have had a large effect. In reality, many correlated phenomena are correlated purely by chance. This gives rise to the well-known saying, “correlation does not imply causation.” (Shortform note: this underlies a lot of popular superstitions, like people who wear their “lucky hats” to baseball games because they think it

IMVU History with Founder Eric Ries (Lean Startup)

The ideas in The Lean Startup came about when Eric got frustrated working on products that failed to get traction. As an engineer, he initially thought they failed due to technical problems, but this was never the right answer. In reality, they just spent a lot of time building things nobody wanted.

Sudhir Venkatesh: Studying Gangs on the Streets

The Myth of the “Crack Millionaires” Let’s set the stage. The 1980’s were marked by a tide of rising crime in The United States. A great deal of the violence in the inner cities was driven by crack-cocaine. According to one study, crack accounted for a shocking 25 percent of homicides in New York City in 1988.

What Is a Red Ocean Strategy?

Much of business strategy in the past few decades has focused on competition, including Michael Porter’s five forces and SWOT analysis. In these red oceans, market structures are known, and companies try to outperform rivals to grab share of existing demand. Over time, markets become crowded, products become commodities competing on price, and profits dissipate. This trend is aggravated by technological improvements that allow incredible creation of supply that can outstrip demand, causing further price competition.

Natural Experiments: Simple Explanation & Examples

Natural Experiments and Economics Economics is not an easy field in which to conduct randomized controlled experiments. Since much of economics focuses on quantities that are very large (national GDP, effects of fiscal policy on employment) and involves the study of individual decisions made by billions of people, it’s rare for economists to be able to test their hypotheses in a lab. For this reason, economists must observe events in the real world that happen create “variable” and “control” groups that can substitute for the classical design of a laboratory experiment. These real world events are called natural experiments. Throughout
