Social Proof Has Limits
What does everyone else using it actually tell you?
The idea
Other people provide information, but popularity is not proof of fit.
In the real world
A popular tool may still fail your constraints.
Going deeper
Popularity is genuine evidence, but about a specific question: whether something works for common cases. It says nothing about the cases that are unusual, and your constraints are the ones you are most likely to think of as normal.
The useful reframe is to ask what population the proof describes. Most companies in your industry use it tells you it handles the industry's typical requirements. Whether it handles your compliance regime, your data volume or your integration is not in that evidence at all, and those are exactly the things that cause a tool to fail a month after adoption.
Where it stops applying
For genuinely commodity decisions, social proof is a perfectly efficient shortcut and independently evaluating everything is a waste. Reserve the scrutiny for choices where your situation is actually unusual.
Why it matters
It separates popularity as evidence about a product from popularity as evidence about your situation.

Test yourself
A tool is used by most companies in your industry, and fails within a month of your adopting it. Was the social proof wrong?
Show the answer
No, it was answering a different question. Wide adoption is real evidence that the tool works for common constraints; it says nothing about the constraints that are specific to you, and those are what it failed.
