Trying new stuff is scary.
Trying new, unproven stuff is even scarier.
So, when we present something new to the world (or even to a single person), we need to stack the odds in our favour.
The risk-adjusted upside needs to be so much larger than the associated costs that the decision becomes a no-brainer.
Especially in the beginning, this may mean overdelivering.
Then, with time, our "new" idea stops being "new", and earns whatever reputation it deserves.
And thankfully, that last bit is within our control.
