Thank you for this  - a fascinating documentary and I am planning on watching the rest in the series.<p>(<a href="http:&#x2F;&#x2F;www.dailymotion.com&#x2F;video&#x2F;xp0tg8_hjernevask-brainwashing-in-norway-english-part-1-the-gender-equality-paradox_news" rel="nofollow">http:&#x2F;&#x2F;www.dailymotion.com&#x2F;video&#x2F;xp0tg8_hjernevask-brainwash...</a>)<p>The above link is from Wikipedia and is a English subtitle - the comedian &#x2F; host wants to know why in Norway there are clear gender divides - 10% women in a construction firm, no men in a hospital maternity ward.  He approaches Norwegian researchers who basically say there is no biological difference, but it&#x27;s cultural (boys clothes in blue etc).  He then points at a road sign with a male worker digging.<p>Then we fly to USA and England, visiting researchers in biological basis of gender difference.  And hey presto there are some.  He amusingly shows English researchers video of Norwegians and vice versa, running his own academic face-off.<p>In the end the Norwegians Coke off worse, being dogmatic about there being no biological basis instead of some mixed approach.<p>Well worth a look.<p>Does it matter? Is there some (testosterone related) difference in empathy that means jobs with more human to human basis (nursing, pre-school teaching) attract women &#x2F; reject men and vice versa for construction &#x2F; IT?<p>Well, yes.<p>Does this mean that you and I and every hiring manager and departmental culture is perfect, balanced, diversity friendly,.  No of course not.<p>The biological basis for our geneder differences is valid and (not being an expert) probably unassailable.  However if there is some scientifically determined geneder ratio for each industry (or even individual job!) is the firm you work in showing that ratio - or is it biased towards some other ratio?<p>That&#x27;s my point - no matter if biology says 50&#x2F;50 or 80&#x2F;20 , I refuse to believe every tech firm out there is perfectly gender balanced and has nothing to learn.<p>Oddly enough, one thing that shines through is that in &quot;poorer countries&quot; (India, Eastern Europe) gender preferences are over-ridden by the simple desire to get lucrative jobs. And anecdotally, there are more non- western women in my Fortune 500 workplace than western.<p>And this leaves the last question - what should be the ratio of men&#x2F;women in software? 10% like construction firms? 50&#x2F;50 like medicine?<p>I doubt this is a simple or solvable question - but Inwoukd always suggest that if you think you are doing it all right and have nothing to learn - you are wrong.
