>In this film universe radar is everywhere and can do anything - find valuable mineral deposits deep underground, locate large schools of fish underwater, etc, and all from thousands of miles away! Worship radar at the church of your choice.
I don't know if radar was developed first, but since sonar accomplishes these tasks I think it's fair to give it to them. Sound/Radio, pretty close.
Agree with people taking the results too seriously, especially with some labs not taking it seriously themselves by failing to handle samples carefully and contaminating evidence.
I like your example regarding souls adhering to photographs, not least because it's something I have chuckled to in my head before :\ .
Lastly, in respect to people's overreaction to results, I'm tempted to dismiss it as amazing that we made it this far, and that our genes carry any meaningful\beneficial signal. This attitude is tempered by my fortunate lack of fatal news, and a chance optimistic outlook [for today at least -- the mind if fickle].
