But it does serve to illustrate the potential for confirmation bias to contribute to preventing or limiting rational management of technical debt. This is, of course, specious reasoning, if it’s reasoning at all. A skeptic wouldn’t even have to read any of these pages to come away convinced that technical debt is at best a controversial concept. Compare this to technical debt which yields only 1.6 million. Searching for there is no such thing as technical debt yields about 300,000 results at this writing technical debt is a fraud about 1.6 million and technical debt is a bad metaphor about 3.7 million. An exampleįor example, anyone determined to find reasons to be skeptical of the need to manage technical debt need only execute a few Google searches. They also tend to underfund technical debt assessments, and set aside advice regarding avoiding debt formation in current projects. Decisions tend, for example, to discount warnings of technical debt issues. The bias favors information that would support directly the achievement of those primary objectives. This causes them to bias their searches for information about technical debt. Most people in these roles have objectives they regard as having priority over eliminating technical debt.

We don’t know why reviews and inspections weren’t as thorough before the loss of the MCO as they are now. One of the many changes resulting from this loss was increased use of reviews and inspections. After the loss of the MCO, an investigation led by NASA uncovered the mix-up. But the team at JPL that was responsible for flying the MCO used metric units. The spacecraft eventually broke up in the Martian atmosphere due to what is now called the “metric mix-up.” The Lockheed Martin team that constructed and programmed the MCO used Imperial units. How confirmation bias can lead to technical debt Computer-generated image of the third stage ignition, sending the Mars Climate Orbiter (MCO) to Mars in December, 1998. Another result is the alignment between preconceptions of the audience and the slant of the newscast for that channel. For example, the homogeneity of cable news channel audiences is a result of confirmation bias.
It also causes us to avoid information that disconfirms our preconceptions. It’s the human tendency to favor and seek only information that confirms our preconceptions.
