Many people, when filtering information or looking for knowledge, instinctively prefer what they call “actionable” content. Anything more general or universal tends to be dismissed as lightweight, empty, or not worth reading.
But both kinds of content have their limits.
A principle that seems to apply everywhere is usually describing a broad, general problem. It is abstract, easy to understand, and easy to remember. The trade-off is that it often loses precision. Because it leaves out the specific situation, it cannot fully explain why something happened in a particular case. When we analyze a real problem, we still have to return to the scene itself and look for both objective conditions and subjective causes.
Highly practical knowledge is different. It is usually much more specialized. It summarizes experience, methods, or rules for a specific problem under specific conditions. Sometimes it is no longer just an opinion, but almost an axiom or even a law within that context. Yet most “actionable” advice sacrifices generality. Move the same conclusion into another field, and it may no longer make sense. It also tends to require more background knowledge, so the cost of understanding it is higher.
Generality, simplicity, and accuracy cannot all be maximized at the same time.
When making an argument, it can be useful to begin with something general: a simple, memorable idea that plants a seed in the listener’s mind, such as “failure is the mother of success.” But that should not be the end of the discussion. From there, the real analysis has to move into a concrete background, with professional judgment and attention to the actual conditions.
The same applies when absorbing information. It is not wise to look only for hard, practical takeaways, nor is it enough to stay with broad principles. The former leans more toward knowledge and theory in specific contexts; the latter often provides methodology, orientation, and guiding principles. Both matter.
