Mr. Damores next move after he explains the reasoning for his biological list is to present this figure right here with a disclaimer. The most basic tenet of selfaffirmation theory Steele, 1988 is that people are motivated to protect the perceived integrity and worth of the self.

Shortly before he produces this figure, he writes Im simply stating that the distribution of preferences and abilities of men and women differ in part due to biological causes and that these differences may explain why we dont see equal representation of women in tech and leadership. Many of these differences are small and theres significant overlap between men and women, so you cant say anything about an individual given these population level distributions. This is a wise move on his part, given that the evidence repeatedly and substantially indicates that most differences between human men and women have wide variances and relatively close means, much more like the first graph on the list than the second. Ill get to several specific cases in a minute. So why does he bring it up at all Mr. Damore says he cares strongly about diversity and womens ability to enter science if they have the aptitude, after all, and I imagine he is trying to drive that point home here. The problem is that the rest of Mr. Damores writing does not reflect that he has internalized this idea. Let me explain. For a graph with two populations distributed along the lines of the upper graph, if you were to randomly sample a single person from each, knowing the gender of each person would be relatively unhelpful to helping you predict which person measured higher in the trait. Now, Mr. Damores distributions are theoretical, but let me show you a quick real world example using human height. Height is definitely a characteristic strongly influenced by biological sex but also is influenced by many other genetic and yes environmental factors, so it makes a particularly ideal example. Lets take a quick look at it. This figure is drawn using data from a CDC dataset taken from 2. In this multinational, doubleblind, randomized trial, we compared vorapaxar with placebo in 12,944 patients who had acute coronary syndromes without STsegment. French psychologist Alfred Binet, together with Victor Henri and Thodore Simon had more success in 1905, when they published the BinetSimon test, which focused on. The truth has got its boots on what the evidence says about Mr. Damores Google memo. American adults from a variety of racial backgrounds Ive simply pulled the mean and standard errors for all adults over 2. Now, youll note that theres considerable overlap between those lines, just as in Mr. Damores first figure. That means that there are some women out there who are taller than some men. Plane Geometry Problems With Solutions here. Not a problematic point, right I should probably note that if I run a quick linear regression of this data in Python with a sample size of 5. CDC, the results are nice and strong p lt 0. Cohens d the statistic used by most of our psych papers of 1. What do these numbers mean I assume that Mr. Damore is well aware of this extremely basic bit of statistics, but if you arent, reader, that means two things. The first number, the p value, is the the chance that we just happened to get a whole bunch of shorter women and a whole bunch of taller men, and this data set is misleading us from the Real Truth that women and men are on average of equal height Those odds are so small as to be infinitesimal in this case, less than one in ten thousand, or roughly three times less likely than a lightning strike. The second number, Cohens D or the effect size, is the difference between the averages of the two groups compared to their standard deviation. Here, the sex of individuals has an effect size of 1. Just to get an idea, you can play with this helpful tool to get a feel for what the different statistics mean here, about 6. That means theres definitely a pretty substantial difference there, and it means that youre well within your rights to assume that if you pull one random woman and one random man, the woman will probably be shorter. Not in every case, of course. But its a reasonable assumption, and its true often enough that you can use it to drive policy without raising any eyebrows. People who are comfortable in tiny airplane seats, like myself, for example very likely to be women. It also means that if you know someones height, you have a pretty good shot at guessing whether theyre male or female, especially if they fall towards one extreme or the other. Not perfect if you could tell perfectly from knowing their height what sex they were, youd have a curve more like Mr. Zte Modem Mobile Partner'>Zte Modem Mobile Partner. Damores second curve, the one he says is bad and wrong. That kind of curve would have a Cohens d of infinity. For additonal reference, anything over an effect size of 0. Mr. Damore is gracious indeed when he draws his curves his populations have an even closer overlap than my figure for human height, implying more overlap between the populations than is the case for height. Thats good as well if we look at the data, thats the case for many traits in which men and women are indeed significantly different. And indeed, Mr. Damores argument sounds like he thinks that personality differences between men and women are distributions that look rather like our mocked up one for height. Its worth noting that statistical significance p values and effect size Cohens d values are not necessarily correlated. For example, it is possible to have a very low p value between two groups with extremely small effect size values, such that there is a difference there but it explains very little of the variation in the population of both groups in meaningful terms. These kinds of results often require sampling a lot of people in each group to even see. This is why it is always important to get a measure of the actual effect size or strength of effect when you evaluate a study that reports statistical significance. My point when I say that Mr. Damore has not internalized this idea is that his figure creates a straw man either there is no overlap, in which case he is being sexist, or. Overlap and some female exceptions to his on average rules exist, in which case we should reduce investment in diversity programs What do those effects sizes actually look like And which pattern do real world gender differences fitLets look at whether or not men and women have different basic values, since that premise is such a fundamental assumption underlying Mr. Damores assertion later on that women value social status and career success less and family and social interactions more. One very thorough study even took the time to rule out cultural differences by testing the stated priorities that 7. When all the data is collated, p values came out very low between sexes but effect sizes came out consistently very small, too, ranging from about a 7. For reference, the example graph Ive placed above has an overlap of about 6. In the researchers own words, Taken together, the four studies lead to the conclusion that men and women differ consistently in the importance they attribute to most basic values. However, the size of sex differences is small, both absolutely and compared with other sources of difference. And the effects of sex on value importance vary substantially across cultures. What they mean by that point is that for every single value, there was a significant interaction effect between cultural and sex specific effects. That means that while men and women might be consistently different, the culture in which they are raised has unpredictable effects on both the direction and the strength of the sex specific acts. For the record, the overall difference between the sexes, again while significant, resulted in Cohens d values of 0.
