Hey there, I'm LiquidFenrir and I've got an idea! When you pick a Kerbal before lauching your rocket, it has two little bars: Courage and Stupidity. When you have a Science lab in your rocket, you can get a little more Sc​ience when you do experiments! But the Science lab needs Kerbals to work. The Kerbals stupidity should have an effect on the science boost! The less stupid they are, the most science you get! This would add an use for the Courage and Stupidity bars which remain useless as far as is know. That's all I have for you, thanks for reading, leave your impressions! --Sorry for bad english
