I appreciate the planning fallacy. I usually do this implicitly but I just changed an expected timeline on a JIRA epic from 80 hours to 160 days after reading this.

80 hours to 160 days? Or do you mean 80 hours to 160 hours?

The article said, “upgrade the units and double the estimate.”

So 20 hours -> 40 days -> 80 weeks -> 160 months

Earlier quoted context omitted.

The article said, “upgrade the units and double the estimate.” So 20 hours -> 40 days -> 80 weeks -> 160 months

so 1 month -> 2 years but 4 weeks -> only 8 months

Nice. This is a good addition to "List of cognitive biases", a Wikipedia article I've liked to read from time to time ever since I discovered it, years ago.

As a Stoic, it's good food for thought to improve your "perception" of life and the world.

Watch out - there is a reverse bias, Parkinson's law, that work expands so as to fill the time available for its completion. This is why Elon Musk sets absurd deadlines he rarely can meet, to resist the expansion of make-work and administrative bloat which consumes longer-timed tasks.

I think this is great! I love to explore how I think by asking myself questions on how I do things, be it decision making or planning.

I created this site which I use to help me figure things out.
