Subjective Understanding is Reduced by Mechanistic Framing

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Philosophy of Science

Background:

• Individuals often possess a superficial understanding of device functionality without deep mechanistic insight.
• A common cognitive bias is conflating functional knowledge (how to operate) with mechanistic understanding (how it works internally).

Purpose of the Study:

• To investigate the relationship between mechanistic and functional understanding of devices.
• To test the hypothesis that conflating these two types of understanding contributes to an overestimation of knowledge.
• To examine how the salience of mechanistic information affects perceived understanding.

Main Methods:

• Experiment 1: Participants viewed either internal components or external views of devices and rated their understanding.
• Experiment 2: Participants answered true-or-false questions on either mechanistic or functional aspects of devices without feedback.

Main Results:

• Viewing internal device parts led to lower self-assessed understanding compared to viewing whole objects.
• Being tested on mechanistic knowledge resulted in lower perceived understanding than being tested on functional knowledge.

Conclusions:

• Increasing the salience of mechanistic details reduces perceived understanding of how devices work.
• The distinction between functional and mechanistic understanding is crucial for accurate self-assessment of knowledge.
• Cognitive biases related to understanding device mechanics can be mitigated by focusing on internal workings.
