If you pay attention to what the others are doing, you are working inside what is socially acceptable in your group and usually you are not going to go against the stablished truth. Hence you will not be able to add any breakthrough to your area of expertise.
Feynman as the post says, experienced this social anxiety once he had the fame. He was able to recognice that you can not truly advance in new topics if you don't ignore social preasure, even if it's self inflicted.
Of course that means that you risk being called a crank, or not getting tenure, or grants for your proyects.
There is huge value in incremental knowledge, but to be Einstein, Watson or Feynman you first need to publish something new that most people will not recognice as valuable at first, if ever...
