LLMs are great at exploring ideas, but they don’t reason from your data. They predict language, not outcomes, so their advice reflects what sounds plausible, not what’s true. Sound decisions require grounding in real evidence; without it, LLMs can be articulate but misaligned with reality.

A model might predict outcomes well within past data yet fail when conditions change. True decision power comes not from predicting what will happen, but from understanding why it happens, so you can act effectively when the future isn’t like the past.

Some decisions are too complicated to be expressed as if statements.
