Forensic Artist to Determine Age? Merely a Joke!

ABC News interviewed a "forensic artist" Lois Gibson on using some "forensic methods" to determine the age of athletes. Those methods include using face ratio, iris opening ratio, etc.

But is it really accurate? How high is the false positive rate (type I error) and false nagetive rate (type II error) with using these methods? Is it reliable to be used as court evidence or for any legal purpose? They didn't bother to tell you. Because...it is far too complicated to tell (really?) or maybe they were just trying to mislead you. Beware!

Professor Arne Ljungqvist, chairman of the IOC medical commission, said
"There are means and ways of establishing the supposed age of a person, but it is not an absolutely *scientificly accurate* way, or *legally accurate* way to do it."
