The Mars-Venus Myth made famous by John Gray in 1992 by the book Men are from Mars, Women are from Venus remains insufferably regnant. Here is a link to a table from the article The Gender Similarities Hypothesis originally published in 2005 in the journal American Psychologist—which is the official publication of the American Psychological Association. The author of the article Janet H Hyde acts as an effective countermeasure foundation for this issue.
To understand the table:
d = score equivalent of standardized gender difference
-d = women are stronger in this area
+d = men are stronger in this area
Observe that the major communication differences between the genders are in the Spelling and Smiling categories with women in the lead by -0.45 and -0.40 respectively. Men take the lead in Conversational Interruption (+0.15 – +0.33) and Assertive Speech (+0.11).
According to the Mars-Venus myth, communication is a significant difference but this is easily dispelled in the most compelling column of all—Effect Size. The most dramatic ‘difference’ is not only Moderate but lies in Spelling and Smiling and so irrelevant that one cannot reasonably cluster men and women on different planets. The Effect Size column differentiation consists mainly of ‘close to zero’ and ‘small.’
Most publications that headline dramatic gender divergence rely on single studies with low sample rates that are understandably misleading. This particular study is an amalgam of numerous studies which take into account a variety of social scenarios. The author is a psychologist who specializes in the statistical technique of ‘meta-analysis’ whose purpose is to substantially increase statistical power by calculating a standard between a group of studies (instead of a small sample size) and analyzing the results.
Unsurprisingly, this research does not amass as much media attention as the Mars-Venus Myth. The media tailors to a market that would rather believe most misunderstandings between the sexes are a result of gender differences instead of poor communication, social dynamics, power struggles, and other factors.
In actuality, the differences between the genders as this study proves are so minute to be essentially redundant for when you examine the scores of the average woman and compare it to the average man, the gap is smaller and less diverse than a comparison within the genders.
Thankfully, Oxford language professor Deborah Cameron has published a book titled The Myth of Mars and Venus to verbally vaccinate against such widespread misconception and ignorance.
