What is means-end chain prioritization?

Example: You have a task on your list: 'Reply to the vendor email.' It has been sitting there for two days and guilt is accumulating. You have no idea whether it is a Q1 or Q4 priority because you have been evaluating it in isolation — as a standalone action with its own urgency. Now trace it upward. Which goal does the vendor reply serve? If it serves your top-ranked objective — securing the partnership that unlocks your Q2 product launch — that email is not a minor administrative chore. It inherits the priority of the goal it feeds. It is effectively a Q1 task wearing a Q4 disguise. But if the vendor email connects to a speculative initiative ranked twelfth on your list, it inherits that ranking instead — regardless of how many days it has been sitting in your inbox, regardless of the guilt. The email did not change. Its connection to a goal changed its priority. Two identical actions — 'reply to an email' — can sit at opposite ends of your priority stack depending on which objective they serve. Without inheritance, you would never see this. You would prioritize both emails the same way: by age, by guilt, by who sent them. With inheritance, the priority is obvious, because you are not evaluating the task — you are evaluating the goal behind it.

This concept is part of Priority Systems in the How to Think curriculum.
