After Clayton Osborn's emotional breakdown, THE WALL STREET JOURNAL reports that the question is floating around if a test could have picked up his vulnerability. Likely the airlines will now have to find such as supposed test and foist it on every employee twice year. It would be wonderful if that does prove to be effective in lowering the risk that passenger safety would be endangered by erratic behavior.
Unfortunately, the wiring in the human brain still presents too many unknowns. In my family why did some members wind up on disability for psychiatric reasons and some get and hold onto responsibility-filled high-paying jobs? Why did some die of alcoholism and others were able to drink socially? Why did some wind up self-destructively in prison and others be totally self-protective? For decades I have been researching this. There are many theories, no answers.
The disturbing reality is that there will always be the Osbons who lose it. If it makes the society feel more secure creating regulations anyway, then that probably has to be.
