Nobel academy head rules out quotas for prizes

The head of the academy that awards Nobel Prizes in science has ruled out introducing gender or ethnicity quotas after this year's Nobel laureates included only one woman, continuing a historic imbalance among recipients.

Göran Hansson, the head of the Royal Swedish Academy of Sciences, said on Monday that he regretted that there were "so few women Nobel laureates" but added the prizes must go to "those who are found the most worthy".

 "We have decided we will not have quotas for gender or ethnicity. We want every laureate [to] be accepted … because they made the most important discovery, and not because of gender or ethnicity," Hansson told the AFP news agency.

The Norwegian Nobel Committee has handed out 609 prizes to 975 laureates since they were first awarded in 1901. Of those, 59 have gone to women, accounting for 6.2 percent of the total.

Investigative journalist Maria Ressa of the Philippines was the only woman honoured this year. She shared the Nobel Peace Prize with Russian journalist Dmitry Muratov.

Hansson, whose remit covers awards for chemistry, physics and economics, said the disproportionate lack of female prize winners reflects historic and persistent "unfair conditions in society".

"There's so much more to do," he said, citing the disproportionate lack of female professors in natural sciences across the world.

"We need different attitudes to women going into sciences … so that they get a chance to make these discoveries that are being awarded."

Hansson said that some progress had been made in recent decades, with the trend of female winners increasing, albeit from a "very low level".
