Despite decades of careful data collection and mathematical and statistical research, on many large questions we have little more than rules of thumb. None of the three seem to follow the rule with any sort of consistency but they are all in the ballpark of the rule, but not by much. The marketer does a statistical test of significance and gets a p-value of 0.04 (remember your business stats class here…). Statistical neglect – instead of subjectively assessing small probabilities and continuously updating them, people choose to use rules-of-thumb (if any heuristics), which can introduce systematic biases in their decisions. With five minutes to speak to the publishers of many of the top science journals, I tried to distill the lessons learned about scientists and social media to a short set of “rules of thumb.” I was not surprised at all when the panel of scientists at the end of the day .. I won't argue the specific merits of the Berkeley study with you, statistical analysis of sociological studies is not my area of expertise. As explained by Moneyball author Michael Lewis, “one statistical rule of thumb in basketball is that a team leading by more points than there are minutes left near the end of the game has an 80% chance of winning. This is simple and is based on underlying statistical calculations (averaged across different scenarios to allow for a simple rule of thumb) that incorporates information about the reliability of the difference score. I find it to be a bit of the pain in the ass to calculate and display (WordPress isn't always cooperative when it comes to efficiently using screen space) the statistical data on everything. The numbers will follow but here are some takeaways (I didn't do any statistical analysis, this is just me eyeballing numbers and drawing conclusions that are probably not statistically significant): The rule of thumb is certainly good in terms of rules of thumb, I wouldn't follow it to the ends o f the Earth but it's definitely better than nothing.
