on: Statisticians Find They Can Agree: It’s Time to Stop Misusing P-Values
There is a significant (pun) difference between statistically significant and economically significant. The conclusion in the drug paper conflates the two. In finance, we could find plenty of statistically significant results (e.g. small cap stocks outperform large cap stocks on Fridays, with a small p-value if you like), but most results were not economically significant--they were not usable for a trading system because they were too small to overcome real-world costs. In short, they weren't meaningful in a real world sense, even though the result was detectable statistically.

on: New Research on Startup Growth
I liked the linkbait - it got me interested enough to click the link (on fivethirtyeight.com), and then I enjoyed the article. Agree that the article title does not match the main theme of the piece--the piece is too long for that anyways. The title for this post is probably too general to get many people interested. There's new "research" on startups written about almost every day.
