I never really understood this argument. It is true that _just_ knowing isn't enough, but, you're pretty limited in what you can do if you don't know.

I guess my case falls apart when it comes to law enforcement. They don't know the law yet they're enforcing it.

I don't know what a wellness circle is. You can't do anything about a problem if you don't know what the problem is.

In general I agree that execution is more than "just" half the battle. There's exceptions though, especially on the audience of HN, which includes a lot of knowledge workers.

For us, it often comes to "I spent 2 weeks investigating this issue, and at the end it was fixed by changing one line of code".

In this case execution was trivial, but knowing what to execute was the 99% part.

This reminds me of the old fable about the repair guy and the hammer where the bill reads:

   Hitting the machine with the hammer                   $1
   Knowing where to hit the machine with the hammer      $149
