It is easy to explain a choice after you know the answer. A short note made beforehand helps you distinguish your original reason from a story that appeared later.
Try the exercise in Train Your Knowing
Use one ordinary sentence
Before submitting your choice, write a reason in your own notebook if you want one: “This color caught my attention,” “It reminded me of the sea,” or “I have no reason; I am choosing it.” Keep it short enough that the note does not take over the game.
You do not need to invent a sensation or make the answer sound meaningful. “No clear preference” is a useful description when that is what happened.
Read the same sentence after feedback
When the game shows its result, return to the note without editing it. Does your later explanation contain something you had not recorded? You can add a separate afterthought while preserving the earlier sentence.
This suggested exercise is about describing a choice clearly. It does not test whether a particular reason causes better guesses.
Finish by noticing whether the note helped or interrupted your enjoyment. Keep it for future play only if it adds something you value.
