Practices that may help
- Audit which constraints are real and which are assumed
List every constraint you’re working under, then test each one for whether it is actually fixed.
Problem Reframing: Solving the Right Problem First - 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 - Scaffolding: The Art of Temporary Learning Support
Scaffolding, a term introduced by Jerome Bruner’s research team to describe Vygotsky’s zone of proximal development in practice, is a set of temporary supports that allow a learner to perform tasks just beyond current ability — with the explicit goal of withdrawing those supports as the learner becomes capable. The evidence across educational settings is strong and consistent. - Build branches that are MECE at every level
Ensure each set of branches is mutually exclusive (no overlap) and collectively exhaustive (nothing important missing).
Issue Tree Analysis - Audit the reference groups driving your spending
Identify whose lifestyle you’re unconsciously trying to match, and question whether that’s your actual target.
Lifestyle Creep: Why Raises Don’t Make You Richer - Decompose tasks and sum the pieces
Estimate each sub-task independently, then add them up — the sum is closer to truth than a top-down estimate.
The Planning Fallacy — Why Your Estimates Are Always Wrong - Test each component probability separately
Before judging a joint claim, estimate each element on its own, then check whether the conjunction is lower.
The Conjunction Fallacy — When "More Details" Feels More Likely - Name the contradiction at the heart of the problem
State exactly which parameter you need to improve and which parameter gets worse as a result.
TRIZ: Systematic Invention and the Logic of Contradictions - Compare two examples side-by-side to extract the underlying principle
Place two worked examples next to each other and find exactly what is the same, structurally, beneath the surface differences.
The Worked Examples Effect: Learn Faster by Studying Solutions First - Trim components to find what you can remove
Systematically ask which components in your current solution could be removed if another component took over their function.
TRIZ: Systematic Invention and the Logic of Contradictions
Does this sound like the set of challenges you might be facing?
- I keep saying "I can’t because of the deadline, the budget, the approval"
- 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’ve broken the problem into pieces but they keep bleeding into each other and I have a nagging fear I’ve left a whole chunk out entirely
- I scroll past what my coworkers and the people I follow are buying and suddenly my own setup feels behind, and I’m reaching for the upgrade before I’ve even asked whether I actually wanted it or just didn’t want to feel like the one falling short.
- I glance at the whole thing and go "yeah, a weekend" without ever listing out the actual steps

- Fermi Decomposition
Fermi estimation is the practice of making rough but principled quantitative estimates by decomposing an unknown into knowable sub-problems, estimating each, and combining them. Named for physicist Enrico Fermi, who was renowned for accurate estimates from minimal data, it is used in science, engineering, and everyday decisions to calibrate intuitions and check whether a number is in the right ballpark — not to achieve false precision.
- Goal Decomposition
Estimate each sub-task independently, then add them up — the sum is closer to truth than a top-down estimate.

- Probability Decomposition
Break the question you cannot answer directly into smaller questions you can.
Decompose the unknown into knowable sub-problems
- Problem Decomposition
Identify the key dimensions that fully describe your problem space before generating solutions.
Decompose the problem into independent parameters
- Technical Contradiction Triz
TRIZ (Theory of Inventive Problem Solving) is a systematic innovation method developed by Genrich Altshuller after analyzing hundreds of thousands of patents. Its core insight is that most breakthrough problems contain a "technical or physical contradiction" — a situation where improving one parameter worsens another — and that inventors across fields resolve these contradictions using a surprisingly small set of recurring strategies.
- Ackermann Method
The Ackerman method, popularized by Chris Voss in Never Split the Difference, is a structured offer-and-counteroffer system. You set a target price, then make a sequence of calculated bids that converge on that target with decreasing increments — signaling that you are near your limit even as you create the appearance of flexibility. The method uses psychology to make your counterpart feel they have won a hard bargain.
