PowerPoint(®) Presentation Flaws and Failures: A Psychological Analysis

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Communication Studies

Background:

• Electronic slideshows (e.g., PowerPoint) are ubiquitous in academic, business, and government settings.
• Anecdotal evidence suggests frequent design flaws, but empirical validation is limited.

Purpose of the Study:

• To empirically investigate the extent to which psychological principles are violated in electronic slideshows.
• To determine if audiences notice and are annoyed by these violations.
• To assess the ability of observers to identify and explain psychological principle violations in presentations.

Main Methods:

• Study 1: Content analysis of slideshows across different fields to identify violations of eight psychological principles.
• Study 2: Survey assessing audience perception and annoyance related to specific presentation problems linked to psychological principles.
• Study 3: Experimental evaluation of observers' accuracy in detecting and explaining psychological principle violations in slides.

Main Results:

• Eight key psychological principles are frequently violated in slideshows, with similar rates across academic, business, and government contexts.
• Audience members report noticing and being annoyed by specific presentation flaws stemming from these violations.
• Observers demonstrate low accuracy in recognizing psychological principle violations and often struggle to articulate the nature of the problem.

Conclusions:

• Effective slideshow design is not intuitive and relies on principles not readily apparent to designers.
• Explicit instruction in relevant psychological principles is recommended for presentation designers across all sectors.
• Improving presentation effectiveness requires a deeper understanding of the psychological underpinnings of design.
