When your A/B test is lying anyway
You randomized correctly and read the statistics honestly, and the experiment can still give the wrong answer, because the clean logic assumes things that are not always true. Learn how users affecting each other breaks the method, why a short test misjudges a long-run effect, how an average hides opposite effects in subgroups, and the reflex of distrusting results that look too good.
Why some markets tip and others never do
Network effects are supposed to produce monopolies, yet plenty of networked markets have several healthy competitors. Learn what makes a market tip toward one winner, the four forces that stop tipping and keep markets competitive, why multi-homing is the quiet enemy of every platform, and how to tell a genuine winner-take-all market from one that merely looks like one.
The chicken-and-egg problem
A marketplace with no buyers has no sellers, and with no sellers has no buyers. Learn how platforms solve the cold-start problem that kills most of them, why the answer is usually to subsidize one side heavily, how pricing in a two-sided market breaks the normal rules of business, and the concrete tactics, from faking one side to going town by town, that actually ignite a network.
The engine that makes winners unbeatable
Some products get better the more people use them, and that single property explains why a handful of platforms dominate the digital world. Learn what a network effect actually is, the difference between direct, indirect, and data effects, why Metcalfe's law overstates the case, and how the same feedback loop that creates a monopoly also makes it fragile at the start.
