Quote of the Day

If lifespan increases simply because one major disease is delayed, then longer survival does not automatically mean that aging itself has slowed. For example, an intervention that extends the lifespan of mice by delaying cancer is fundamentally different from one that slows the gradual decline of many body systems, even if both produce similar survival curves.

Scientists Say Conquering Age-Related Diseases Could Dramatically Extend Human Life

When stated this way it is obviously true. One might be tempted to make light of this. But correctly expressing something obvious can be very difficult when no one has ever had the viewpoint from which the truth is obvious.

The article this QOTD came from is an example of something I have talked about before: The necessity of an accurate problem statement. You can call it a simple thing. But it may be a profound change in mindset which enables rapid progress toward a far better solution.

I would like to thank my engineering professors from several decades ago for this enlightenment. One of the first things taught in Engineering 101 was how to write an engineering report. And the first thing in a such a report was the problem statement. That problem statement was to be written before you took your slide rule out of its case or looked up the gain bandwidth product of the cool new operational amplifier you heard about a few days ago and were itching to find a use for.

This can be illustrated more simply with the adage, “Give a small boy a hammer, and he will find that everything he encounters needs pounding.” Technically, this tendency is a form of cognitive bias called Law of the instrument. Writing an accurate problem statement is one means to overcome this bias.

This simple thing can make a huge difference in every problem you need to solve. It is not limited to aging, gun owner rights, politics, interpersonal relationships, or engineering. First, think about what you are trying to solve, not how to make a solution work.
