...is what people see when they look ahead. They'd rather generalize and assume that's how things typically work. It's easier for them to see the big picture than think about all the subtleties in between.
The world may be flat but what about the differences found underneath, inside, over, and above? Sometimes it's the things that people don't see that matter the most, such as the guts of a computer.
Generalizing works to understand things at a macro-level. It fails, however, in uncovering the minutiae. No two things or people are exactly the same. Exploration challenges popular assumptions.
Things are best understood looking from the different angles rather than at surface level.
