I was just thinking that if a study was proposed to achieve the same ends using drugs or, say, some kind of behavioural conditioning, it wouldn't get ethical approval.
That's the exact opposite of this 'experiment'. This is saying that rather than force a cultural expectation onto children, let's let them grow into whomever they feel they want to be. This is deliberately attempting to avoid conditioning, not to enforce it.
Culture changes all the time, let it do its job.
We are - culture, at least in modern Western democracies, is moving towards a culture of personal liberty and freedom, where people have the space and right to grow as they choose, not to be constricted or defined by other people's conceptualisations of what they should be.
This is like trying to stop people liking pop music by letting them listen to nothing but opera.
No, this is like saying to people you can listen to whatever music you'd like, and though some pretentious purists will tell you that classical is the only music you need, and social movers and shakers are all about milking your money through what they're pushing through the charts, you have access to the smooth jazz selection if you'd like...
