Reasoning and diagnostics Part II

In this issue, Barney Donohew explores critical thinking
Published:  13 March, 2017

We began this journey last issue, so to recap: We need solid reasoning skills to carry out effective diagnostics; persistently good decision making doesn't happen by chance. Possibly out of convenience these skills are often underestimated and undervalued by people, both in and out of the trade. We must raise awareness of the discipline and precision of thought necessary for logical and critical thinking: so we can be better rewarded for our efforts; and to make sure they are consistently and properly applied.

Reasoning, arguments and hypotheses
We covered some fundamentals in my last article: we explain our reasoning using arguments, which contain statements supporting a conclusion; one type of argument, a deductive argument, should guarantee the truth of its conclusion (if it is sound); however, we need to use critical-thinking to check this, by making sure i) there are no other possible conclusions (which makes it a valid argument) and ii) the supporting statements are true.


Reasoning and Diagnostics Pt 1

Diagnostics is all about decisions. And what is a decision? It is a conclusion or resolution reached after consideration. Therefore, efficient and effective diagnostics is about drawing the right conclusions at the right time. How do we do that? Amongst other things, by making sure our logical and critical thinking skills are up to scratch. This series of articles aims to help us with that by looking at the principles of human reasoning.

If you've been reading this magazine for any amount of time, you'll be well aware of the obvious benefits of using an oscilloscope when diagnosing faults, but it is the less obvious benefits that with practice can lead to the correct diagnosis.
