For all practical decision-making purposes, we need to treat measurement as observations that quantitatively reduce uncertainty.

Anything you need to quantify can be measured in some way that is superior to not measuring it at all. --Gilb's Law

The commonplace notion that presumes measurements are exact quantities ignores the usefulness of simply reducing uncertainty, especially if eliminating uncertainty is not feasible (as is usually the case).

The first 100 samples reduce uncertainty much more than the second 100. In fact, even the first 10 samples tell you a lot more than the next 10. The initial state of uncertainty tells you a lot about how to measure it.

Given a particular observation, it may seem more obvious to frame a measurement by asking the question, "What can I conclude from this observation?" or, in probabilistic terms, "What is the probability X is true, given my observation?" But Bayes showed us that we could, instead, start with the question, "What is the probability of this observation if X were true?" The second form of the question is useful because the answer is often more st..

If you don't know what to measure, measure anyway. You'll learn what to measure.

whether a finding is statistically significant is not the same thing as whether your current state of uncertainty is less than it was before or what the economic value of that uncertainty reduction would be.

When presented new information, we have no other option than to relate it to what we already know--there is no blank space in our minds within which new information can be stored so as not to "contaminate" it with existing information. --Clifford Konold, Scientific Reasoning Research Institute, University of Massachusetts"

A cybersecurity expert can become well versed in technical details such as conducting penetration tests, using encryption tools, setting up firewalls, and much more--and still be unable to realistically assess their own skills at forecasting future events.

The Likert scale. Respondents are asked to choose where they fall on a range of possible feelings about a thing, generally in the form of "strongly dislike," "dislike," "strongly like," "strongly disagree," and "strongly agree." Multiple choice. Respondents are asked to pick from mutually exclusive sets, such as "Republican, Democrat, Independent, other." Rank order. Respondents are asked to rank order several items. Example: "Rank the foll..
