How do you structure this prompt?

Hello,

I came across this question in one of the online blogs and thought it was very interesting.

"An asteroid is going to hit the earth and destroy 100% of it. You have several options: create a missile to destroy it (blowing it into several particles which will still impact the earth but destroy only 50%), or create a missile to push it out of the way (this only has a 50% chance of working though). Which alternative do you pick?"

How do you structure something like this? What is the expectation for a prompt like this? Is it sufficient to just lay out an approach or is it an estimation of probability type of case?

Thanks.

I have a question for you: What's the expected value (EV) in each of these scenarios?

They're the same. As such, no, it's not succifient to lay out estimation of probability.

I have another question for you: did you clarify the objective?

Clarify objective - are we trying to save humanity? Are we ok with living with 50% of the population dead?

It's all about objective here...the rest follows.

I won't provide a further framework as i think you should create it yourself with this objective in mind....post it and we'll review :)

Additionally, I've created a case with a very similar sort of dilema/thinking. Try it to see how you might think about the entire problem:

Hi Ian, thank you for your thoughts. The way I am thinking about this is as follows: Supposing that the objective is to save humanity, I would like to look at four broad factors - Technical aspects related to missiles, Human capabilities, and trade-offs. 1. Technical aspects - a. difference between technology of both missiles; b. how much time will it take to build each missile; c. Is it better to build one vs the other in terms of resources available; 2 - Human capabilities - a. Does it need international cooperation? If so, what is the timeline; b - is there a conflict of interest between countries; c - who will lead the mission; d - technical expertise; e - prior experience; trade-offs - a. difference between quality of life; b - can we say which 50% part of the world will be destroyed eg: Antarctica vs America? I apologize for the funky formatting. I am unable to do it the usual way. I would love your feedback on this structure. Thanks — ABCD on Jul 01, 2020

Hi!

I agree with Ian - it is all about the objective. If it is

  • Avoid the extinction of humanity!

then there is a clear logic for the decision.

  • You will avoid extinction of humanity with 100% probability in scenario 1 (even though it will come at the cost of having half of the planet devastated).
  • You will only avoid the extinction of humanity with 50% in scenario 2.

So given the above objective, Scenario 1 appears preferable in rigorous terms.

Alternatively, you can also look at it through a "value at risk" lens.

  • In scenario 1, only 50% of the earth is at risk.
  • In scenario 2, 100% of the earth is at risk.

So again, rigorous logic leads to choice of scenario 1.

Cheers,

Sidi
