Coaching practices for Hypothesis Testing in Practice

Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Hypothesis Testing in Practice, these are the strongest matches in the current practice library.

Does this sound like the set of challenges you might be facing?

• I keep trying things and then telling myself afterward that they "kind of worked"
• I keep gathering more and more data without ever deciding what would settle the question, so the research just sprawls on forever and I’m collecting whatever turns up instead of hunting for the specific thing that would prove or kill each possible explanation.
• I showed it to people and everyone said they liked it, but somehow that told me nothing
• I keep waiting for one clean lightning-bolt answer about my purpose before I’ll commit to anything, and it never comes
• I have all these confident hunches about how things will turn out, but I never commit to a specific call in advance

Practices that may help

1. Write the hypothesis before you act
   State what you expect the experiment to reveal before it begins.

2. Test branches by forming specific, falsifiable hypotheses
   Turn each branch into a testable hypothesis before gathering data.

3. Test — let users break it
   Put the prototype in front of real users and treat their confusion as data.
   Design Thinking, Step by Step
4. Treat the Hedgehog as a hypothesis that iterates
   Write your best current intersection as a testable hypothesis and update it when new information arrives.
   The Hedgehog Concept
5. Make bold predictions — then check them
   State a specific, testable prediction about the future and record it before you see the outcome.
   Falsification Thinking
6. Update beliefs by degrees, not wholesale
   Treat new information as evidence that shifts probabilities, not as proof that changes everything.

7. Search deliberately for the black swan
   Look for the single example that would overturn your generalization.
   Falsification Thinking
8. Test your updated model in new situations
   Design a small experiment that would confirm or disconfirm the principle you just derived.

9. Run low-cost experiments on intersectional ideas
   Test cross-domain ideas quickly and cheaply before investing in them fully.

10. Designing the Experiment
    Plan a real-world activity that will generate clear evidence for or against the belief.
