A recent amusing Twitter exchange between myself, colleagues, and a chap who writes for an online magazine reignited some thoughts I had about the interplay between scholarly discourse and public perception. You may recall that there were recent reports about an Australian couple obtaining surrogacy services in Thailand. When it turned out that of the twins that the surrogate was expecting, one was diagnosed in utero with Down’s, a chain of events was set in motion which led to the Australian couple departing with the non-Down’s twin only, leaving the other twin behind. Read all about it here. I am not going to go through all of the reported issues in this blog post. The, brief, point I seek to make here is another.
