Earlier this year, a group of prominent Australian scientists came forward to question the so-called "New Zealand Protocol 01" that allows New Zealanders to freely immigrate to Australia. On April 6, 2007, 60 scientists wrote a letter to the Australian Prime Minister asserting that the intelligence amongst the general population is deteriorating due to intellectually void New Zealanders immigrating to Australia.
“Observational evidence does not support today's computer models, so there is little reason to trust model predictions of the future… Significant [scientific] advances have been made since the [NZ01P] protocol was created, many of which are taking us toward a concern about the decreasing intelligence amongst the general population. If, back in the mid-1970s, we knew what we know today about immigration, NZ01P would almost certainly not exist, because we would have concluded is not necessary,” the 60 scientists wrote. See:
