The Lens in Your Hand
Picture a quiet observatory at night. You step up to a massive telescope that holds a universe of data. In your hand sits a small glass eyepiece. This lens is your question, the specific prompt you need to bring a distant, blurry star into focus.
Just as you try to slot the eyepiece in, a safety shutter slides shut. It forces a pause. A diagnostic light scans the glass in your hand and reveals a flaw. The lens is subtly warped, shaped to bend light toward what you expect to see rather than what is actually there.
You realise you were about to ask a leading question that would distort the answer. Guided by the system's feedback, you polish the lens. You smooth out the curve until the glass is neutral and clear, removing your own assumptions before the machine even looks.
With the corrected lens in place, the shutter opens. The star field appears, but with a glowing digital map overlaid on top. This map traces the path of the light, connecting the shape of your lens to specific scratches on the telescope's internal mirrors.
You step back, understanding that a clear image isn't about finding a perfect machine. It is about seeing the distortion in both the tool and the user. True discovery requires constantly checking the glass in your own hand.
