"Frankness" is considered a virtue, but in reality, it is a form of "thought laziness" and "the arrogance of the strong."

Being frank means being unwilling or unable to understand others' linguistic systems: expression and comprehension, that is, output and input.
Language can be learned, and discourse systems can also be learned. It’s important to understand what others need in order to achieve your own goals.
Between people, worldviews and values are difficult to align. Understanding how others think and what they need is like learning a new language.
Some people care about logic and facts, some care about vision and values, and others care about tone and feelings. Those who focus on facts tend to achieve worldly success easily; those who focus on values often have a philosopher’s temperament; and those who focus on feelings tend to have a sensitive inner world.
In negotiations, facts, values, and feelings—these three dimensions—will always have a breakthrough point. And each person’s tendency varies. When aligned, they appear strong; when opinions differ, they show weakness.

Tone and feelings: UI/UX
Vision and values: product expression
Interestingly, often showing weakness is a form of strength. The more confidence you have, the more effective it is to show weakness.
Showing weakness is about going with the flow. What others need, you provide. Water benefits all things without competing, and thus is close to the Way.
