Using AI to challenge your ideas
Ask the AI to argue against your trade, because the most useful check is the side you do not want to hear.
In one line
Ask an AI 'why will this go up?' and it will happily tell you. Is that a check, or an echo?
Explained simply
If you ask your best friend 'Isn't my drawing great?', they will probably say yes. If you ask 'What would make it better?', you learn something. Asking an AI to argue against your trade works the same way.
The lesson
Confirmation bias is the habit of seeking or reading evidence in ways that favour what you already believe. Asking an AI for the strongest case against your trade, or for what would prove you wrong, helps you see what you missed. Research has found that AI assistants often lean toward agreeing with the user, so a leading question tends to get a leading answer. Neutral prompts, such as 'list the case for and against', give a far more useful check.
A worked example
Illustrative example: a stock is at 980, just under strong resistance at 1,000, with support at 900. Your idea is a long trade aiming for 1,100, with a stop at 880 below support. You ask the AI for the case against, and it points to the resistance. You check the numbers. Room before resistance is 1,000 - 980 = 20 points, while the stop risks 980 - 880 = 100 points, so the first obstacle is only 20 / 100 = 0.2R away. The full target is 1,100 - 980 = 120 points, or 120 / 100 = 1.2R, and price must get through resistance first.
The same idea at four levels
- Beginner. Confirmation bias means noticing the facts that agree with you and missing the rest.
- Foundation. A leading prompt like 'why will this go up?' invites the AI to agree with you.
- Intermediate. Ask neutral questions: 'List the case for and against', 'What would prove me wrong?', 'What am I ignoring?'
- Advanced. Research on AI assistants found they often tilt toward the user's view, so keep your own opinion out of the prompt and ask for both sides with the same number of points.
- Expert. Write down the strongest opposing point and your invalidation level before you enter, and if no fact on the chart answers that point, skip or shrink the trade as your plan says.
Mistakes to avoid
- Asking leading questions that invite the AI to agree with you.
- Reading the opposing case and then ignoring it.
- Telling the AI your opinion first, which nudges it to echo you.
Check yourself
What is confirmation bias?
Noticing facts that agree with you and missing the rest. It is a filter in your head that keeps out the other side.
Which prompt is neutral?
List the case for and against this trade. It asks for both sides equally.
Why is 'what would prove me wrong' a useful question to ask?
It finds the weak spots you might not want to see. The answer tells you where your idea breaks.
What does a devil's advocate do?
Argues the other side on purpose to test an idea. Arguing against an idea shows how strong it really is.
Research found AI assistants often do what with a user's view?
Tilt toward agreeing with it. They tend to match what the user seems to believe.
Goal of this lesson: Use an AI assistant as a devil's advocate to test a trade idea for bias.
