Too true to stay boring
The Beauty of Tautologies
Why saying the obvious just started a surprisingly heated money fight
TLDR: The article argues that obvious-by-definition statements can still clarify how markets and money work, especially by showing why bad explanations fall apart. Commenters were torn between calling it essential reading for politicians and dismissing it as elegant but limited wordplay when real policy gets complicated.
A post about tautologies — basically statements that are true by definition — somehow turned into a mini-comment war about whether "the obvious" is actually the secret to understanding money, markets, and government policy. The writer’s big point is simple: boring truths can still be powerful. Saying that every stock sold is also bought may sound pointless, but it helps expose sloppy headlines blaming crashes on a vague "selling wave." In plain English, prices move because people react to new information, not because selling magically exists without buyers.
And the comments? Absolutely split between "this is essential reading" and "calm down, it’s still just a tautology." One fan declared tautologies "beautiful," which is either charmingly sincere or the most tautological comment ever posted. Another said economic leaders should be forced to read this, turning the thread into a low-key roast of finance ministers everywhere. But skeptics pushed back hard, arguing that these neat word equations may catch bad logic, yet fall apart when real-world policy gets messy — especially when even defining "money" has become a nightmare.
There was also some delightful nerd comedy in the mix, with one commenter name-dropping Arthur C. Clarke’s line about advanced tech looking like magic, basically saying: yes, tautologies are fun, but please, not too many before breakfast. So while the article tries to rescue a badly mocked idea, the real drama is in the crowd reaction: are tautologies underrated truth machines, or just elegant ways to sound smart while avoiding the hard part?
Key Points
- •The article argues that tautologies do not establish causation but are valuable in economics because they clarify reasoning and constrain plausible explanations.
- •It uses the stock market identity that shares sold equal shares purchased to argue that market declines cannot be explained by selling alone.
- •The article says overnight changes in stock indices while markets are closed show that prices respond to new information rather than trading activity itself.
- •It identifies six economic tautologies for analysis and states that policy arguments often use such identities to support broader models.
- •In its monetarism section, the article says the Cambridge equation is more intuitive than the Equation of Exchange because it links NGDP to the money supply and the share of income held as cash balances.
