"You can position facts at two poles: political facts and technical facts. A political fact is true if enough other people believe it to be true; for example, who the president is or where the border of a country is. [...] Then, on the other side, some things are purely technical. A technical fact is the result of an equation or the diameter of a virus under an electron microscope—the result of physical constants. What people think does not change technical truth. Physical facts are independent of any human being. An alien would come to the same conclusions." - Balaji Srinivasan
1+1=2 even if no one believed it. It's a truth you discover. "The New York Times is a reputable media you can trust" is a truth that can change over time. It's a truth you create.
Generally, technical facts are found in hard sciences, and political facts in social sciences. Technical facts, in business, are the actual physical performance and specs of a product, while marketing & use cases ("great for busy professionals") are political facts. In investing, many technical people express their disgust when a company is worth more than "the fundamentals" suggest, simply because they don't realize that if enough people believe the company to be worth $500m, it will be worth $500m (until they stop believing it).
Unless you work purely on hard, technical stuff, you should consciously remember that another form of "truth" exists: truth from popularity. Of course, a key to innovation and large success is knowing that this truth isn't definite. Peter Thiel's famous interview question comes to mind: "What important truth do very few people agree with you on?"
High agency, independent-minded people naturally divide the word into political and technical facts. They often find themselves asking "is this an actual, physical impossibility, or simply a social construct?" They reason forward from first principles, while conventional-minded people think backwards from social cues.
