I agree. Hacker News readers are more logic based but the rest of the world is more emotional based. For most people, the emotional half of the brain dominates the logical half of the brain. I think we can agree that being invested in a diverse basket of 20+ stocks with 5% or less of the portfolio invested in each is regarded as a pretty safe bet. I also think we can agree that anyone who invests will do better in the long run than people who don't invest.
The news commonly sells convincing chichen-little fear that the sky is falling, the market's gonna crash, and we should all flock to gold. But I know with higher certainty that Amazon will keep shipping packages, Target will keep selling merchandise, Apple will keep selling more iPhones, and VISA cards will keep collecting interchange fees.
We can debate though whether it's better to hold an index fund you might panic sell or individual stocks that you plan to hold forever.
