In 2040, I will spend some time reviewing the current state of expert discourse regarding innate psychological differences by biological sex. This review will consist of light-to-moderate internet reading, browsing studies that have been completed, and requesting the assistance of any personal acquaintances that can best help inform me. 

I will make a subjective judgment regarding the "experts" on this topic as of 2040, which will likely be a list of individuals who I (with the help of light research) consider best-informed in that future period. 

There needs to be expert "consensus" for this market to resolve. If there is no consensus, I will update the market close timing to be 5 years in the future. I will continue to push out the close date until there is expert consensus. A rough approximation of consensus from my perspective is ~80% of experts voicing roughly the same thing. 

I will interpret "strong" subjectively. I don't have a great threshold in mind, but I can try to respond to questions in the comments section if helpful.  

By "innate" I am referring to the nature/nurture question (i.e., without regard to societal priming). 

I am referring to "biological sex" at birth - not gender. 

I'm not particularly knowledgeable about this subject as of market creation, but my rough understanding is that - as of market creation - there is no expert consensus on this question. 

I may "n/a" and/or "unlist" this question preemptively if it becomes a comment cesspool or if my quality of life decreases for having created the market.
