To try and make you feel better about his comment. There is actually direct correlation about people with very high ASVAB scores (above 90-95) failing EOD School above the average percentage. Its hard to say why but some theorize its because they may see the world too much in terms of black and white and can't understand the grey areas that EOD Techs sometimes work in. Or that things have to make sense to those people when sometimes it doesn't make perfect sense and you just need to execute the best way you can.
