Does this sound like the set of challenges you might be facing?
- One compelling story or one impressive candidate completely swings my whole read, and afterward I can’t tell whether real new facts moved me or I just got swept up in how vivid and memorable that one case was.
- I build my estimate from my own optimistic story first and only glance at how long these things usually take at the very end as a sanity check
- I’m about to commit to this timeline and on paper it all looks fine, but I have a nagging feeling I’m glossing over the ways it could go sideways because admitting them now feels like talking myself out of it before I’ve even started.
- I can feel something hard coming but I keep it deliberately fuzzy in my mind because looking straight at it is uncomfortable
- I’m about to launch into something and I keep estimating how it’ll go off the handful of vivid winners in my head
Practices that may help
- State your estimate before encountering vivid case information
Lock in a prior probability estimate before reading a compelling story or meeting a specific candidate.
Attribute Substitution: When Your Brain Answers a Different Question - Anchor on the base rate before adding inside-view details
Start your forecast from the class median, then adjust — do not start from your narrative and adjust to the base rate.
Reference Class Forecasting - Run a premortem before committing
Imagine the project has already failed and work backwards to find why.
The Planning Fallacy — Why Your Estimates Are Always Wrong - Describe the difficult situation specifically and realistically
Spell out the scenario you are anticipating — who, what, when — without minimizing or catastrophizing.

Find the statistical base rate for the category your decision belongs to — not just the inspiring examples.
Survivorship Bias: Learning from What You Can’t See - Invoke the outside view before committing to any significant plan
Before finalizing a plan or forecast, ask "How did similar things go?" as the first checkpoint.
The Outside View - State your prior probability before seeing the evidence
Before looking at any data, commit to a numerical estimate of how likely something is.

- Cope Ahead Scenario
Cope ahead, a DBT skill developed by Marsha Linehan, involves mentally rehearsing a likely difficult situation in detail — imagining the emotions that will arise, and practicing the exact coping responses before the event. It is not positive visualization; it is stress-inoculation rehearsal that pre-loads effective responses so they are available under real-time pressure.

Before estimating, look up how long similar past projects actually took — not how they felt.
Reference class forecasting
- Hindsight Bias Prevention
Hindsight bias is the tendency, after an outcome is known, to believe you would have predicted or expected it all along — making the world seem more predictable than it was. It is one of the most replicated effects in judgment research and quietly corrupts feedback, performance reviews, and lessons learned, because we evaluate decisions by their outcomes rather than by the information available at the time.

Before starting, assume the plan has already failed and ask why — then fix it now.
