"A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools"

This quote by Douglas Adams is a reminder that no matter how sure-fire a style might seem, it is still possible for someone to find a method to misuse it. Adams is recommending that when creating something, it is essential to consider the potential for misuse by those who might not have the exact same level of understanding or knowledge as the designer. He is warning versus underestimating the ingenuity of those who may not have the exact same level of intelligence or understanding as the designer. Adams is recommending that even the most foolproof design can be misused if the designer does not take into account the potential for misuse. This quote acts as a pointer that no matter how sure-fire a design might seem, it is still possible for someone to discover a method to abuse it.
