It could be that something about Linda reminds the twins of somebody or the name Betty or they like the sound of the name.

I don't know the answer to the question, but at least it gives us some way of thinking about things beyond just sheer coincidence.

There were no laws being broken, but there was a very difficult moral and ethical line that was being crossed.

And I've interviewed a number of experts in the field of bioethics, and they've made a very clear distinction between legal and moral issues.

And just because something is legally acceptable...

It doesn't mean that morally you should do it.

Just because you can doesn't mean that you should.

And as far as I'm concerned, I think this stands as an excellent example of how not to do research.

Well, you probably could never get this past the IRB or what is called the Institutional Review Board at your institution.

Every university or research outfit maintains a committee that reviews proposals and research outcomes and things of that sort.

And to say that you're going to intentionally separate twins would never, never fly.

And if you went ahead and did it anyway, if you intentionally separated twins, I think you could get into a lot of trouble.

I don't know if there's actually a law against that.

You know, but nevertheless, I think that you would be violating the agreement between you and the university.

So in a sense, you could be breaking a law.

It was really not designed well enough to tell us anything because they had very small numbers.

Now, they did do repeated IQ testings.

And in fact, I have access to two of the files because the twins sent them to me.

And I look at them.

I'm interested in them.
