People wouldnt fly personal aircraft-or participate in many other activities-if there werent benefits. Thats human nature. Some benefits we seek by taking risks are intangible and hard to quantify. Others can be readily identified and weighted. Its a calculus we all employ daily in mundane ways. However, the problem isnt that we fail to assess benefits when we analyze risk. Instead, the issue is the inaccurate values we assign on both sides of the equation.
