This appalling fat cat wants to shut the door on all my mature students, many of whom left school after GCSE and give up a lot to go to university. I can tell him that theyโ€™re the hungriest for education and far from being unable to graduate, they regularly get the highest grades. Hateful man.

Dear Sir Paul,

Re: Royal Society Code of Conduct

I am sure that many scientists have written to you about the specific question of Elon Muskโ€™s Fellowship and whether, under the Royal Societyโ€™s Code of Conduct, his retaining that Fellowship is appropriate. I will not rehash these issues.  Instead, as a female scientist with extensive experience of activities aiming to increase equality, diversity and inclusion in the engineering and physical sciences sector, I am writing to you (in a personal capacity) to ask you to reconsider the statements you have recently made in this context to the UK press about the Royal Societyโ€™s Code of Conduct and how it is applied.  

A 2018 report  from the joint National Academies of the United States of America, concluded that โ€œsexual harassment is common in academic science, engineering, and medicineโ€ and that โ€œgreater than 50 percent of women faculty and staff and 20โ€“50 percent of women students encounter or experience sexually harassing conduct in academiaโ€.  This report described codes of conduct that make clear that sexual harassment is unethical and will not be tolerated as a โ€œpowerful incentive for changeโ€. The authors also noted that sexual harassment can have significant and damaging effects on the integrity of research.  In my own praxis, I have found that clear and consistently-implemented codes of conduct that address these issues make female scientists and engineers safer, and allow them to focus more effectively on their research.  For codes of conduct to have such a positive effect, it is vital that sanctions for actions which transgress the code are meaningful and substantial.

I was hence aghast to realise that in an interview with the Financial Times  published on 9/1/26, you appear to have suggested that the Royal Society โ€œshould only expel fellows if their science proved โ€œfaulty or fraudulent or highly defectiveโ€โ€.  Moreover, in a further interview with the Guardian  on 11/1/26 you suggested that the code โ€œmay need to be looked at againโ€, with the implication that your aim would be to remove the option of sanctions on Fellows for reasons not strictly related to faults or defects in their research. 

I suggest that changing the Royal Societyโ€™s code of conduct so that the likelihood of serious sanctions for sexual harassment is reduced, would directly endanger women who interact with the Royal Society at events or otherwise, and would provide a licence to harass to the already powerful people on whom the Society bestows fellowship.  The implications of your words - that under your leadership the only infringements of the code which are likely to receive the sanction of the Fellowship being removed are those related to research misconduct - already risk empowering harassers.  You stated, in the Financial Times interview, that โ€œthereโ€™s many bad people around, but they have made scientific advancesโ€.  Given this awareness of the possibility of bad actors in our scientific community, it is wholly irresponsible to suggest that the Royal Society would not act to sanction these people if they harass more vulnerable scientists.

I am hence writing to request that you retract any suggestion that the Societyโ€™s Code of Conduct should be changed so that the only reason a Fellow might be sanctioned by the removal of their Fellowship is โ€œfaulty or fraudulent or highly defectiveโ€ research.  This action is necessary to safeguard female scientists, a requirement placed on the Society by safeguarding legislation and UK statutory guidance. 

Yours sincerely,

Professor Rachel A. Oliver.

Following coverage over the weekend of Sir Paul Nurse's comments that suggested that the only reason that a Fellow should be expelled from @royalsociety.org is scientific misconduct, I have written to him to explain the risks such an attitude poses of increasing sexual harassment in STEM.

My dad abhors any negative comments about immigrants. Asked him recently why heโ€™s so strong on it: โ€˜Because weโ€™re always happy to take the rich and clever ones. Which means itโ€™s not about disliking immigrants. Itโ€™s about disliking the poor and vulnerable. And thatโ€™s a bad human instinct.โ€™
