Probability Estimation

Anxiety often overestimates how likely a feared outcome really is. This exercise helps you identify a worry, examine the actual evidence, and calculate a fairer, more realistic estimate.

🎯 Name the Fear

Identify a specific feared outcome and rate how likely it feels right now, before examining any evidence.

⚖️ Weigh the Evidence

List the real evidence for and against the outcome — focusing on facts rather than how the worry feels.

📉 Revise the Estimate

Re-rate the likelihood with the evidence in front of you. Fears often shrink once you see the facts clearly.

1

Feared Outcome

What is the specific outcome you're worried might happen?

2

Initial Likelihood

Before looking at any evidence, how likely does this outcome feel right now? (0–100%)

50%
3

Examine the Evidence

List the real evidence on both sides. Focus on facts, not feelings.

4

Revised Likelihood

Now that you've weighed the evidence, how likely is the outcome really? (0–100%)

50%
💡 Notice the gap between your first estimate and your revised one. That difference is the space anxiety was filling with worry rather than fact.
