Are you writing a paper, or an article? If the latter, by all means gather together reports (if they exist). But if the former, it seems to be begging the question, assuming that there is significant evidence that GPS erodes situational awareness - assuming your "I learnt about flying from that" is a general problem. GPS is, as is hinted by one of the posters, a system that's substantially more reliable and accurate than most others. It doesn't absolve you from remembering that you are in an aeroplane - any more than normal law on an Airbus means you can ignore the fact that you've got 60+ tonnes of metal and plastic strapped to your bottom.
