THE PSYCHOLOGY BEHIND STRESS & ANXIETY

Intolerance of Uncertainty

Why not knowing can increase anxiety

Explore the difference between useful preparation and the exhausting search for guarantees. Choose scenarios, experiment with uncertainty and build your own supportive plan.

1 · Understand the pattern

When an outcome is unknown, the mind may predict danger. Repeated checking or reassurance can offer short-term relief, but the doubt may return.

Uncertainty → Worry → Checking or avoidance → Brief relief → More uncertainty

This is a learning illustration, not a diagnosis. Clear communication and accessibility adjustments are valuable supports.

2 · The “What if?” explorer

Automatic prediction

What do I actually know?What useful action is available?

3 · Uncertainty experiment

Explore how different responses can affect a fictional worry cycle. This is not a clinical score.

Try both routes and notice the difference between temporary certainty and a manageable next step.

5 · Build your personal plan

6 · A compassionate reminder

You do not have to feel certain before taking a small, considered step. Equally, asking for predictable information, clear instructions and support is reasonable. The goal is flexibility, not forcing yourself to tolerate avoidable barriers.
