Key Findings

  • 01A variety of approaches are employed to represent risk to research participants.
  • 02Key methodological, ethical, and research challenges exist in representing and assessing security and privacy risk.
  • 03Guidelines for reporting user studies in security and privacy are needed.
02

Application

Design takeaway

When designing user studies involving security or privacy risks, explicitly document and justify the chosen method for communicating those risks to participants.

How to apply

When planning a user study that involves potential security or privacy risks, consider the trade-offs between different methods of risk communication (e.g., scenarios, prototypes, direct explanation) and their potential impact on participant behavior and understanding.

Project actions

  • 01When designing your own user study, think carefully about how you will explain any potential risks to your participants.
  • 02Consider whether your explanation is clear, accurate, and doesn't unduly influence their behavior.
03

Method & Evidence

AimTo systematically review and analyze the empirical methods used for representing risk in usable privacy and security research, identifying their benefits, shortcomings, and ethical challenges.
MethodSystematic Literature Review
ProcedureA systematic literature review was conducted on 284 full-length papers from five top conferences (2014-2018) that included human subjects studies related to security/privacy and usability. The analysis focused on study methods, risk representation, use of prototypes/scenarios/interventions, deception, and participant types.

Strengths & Limitations

Strengths

  • +Comprehensive systematic review covering a significant period.
  • +Focus on empirical methods provides practical insights.

Limitations

The review's findings are based on published literature, which may not always reflect the full spectrum of methods used or the nuances of their application in practice.

Reliability & validity

The systematic review methodology enhances reliability by using a structured approach to paper selection and analysis. Validity is supported by the focus on empirical methods and the identification of challenges, though the subjective nature of risk perception can introduce variability.

Think critically

Given the variety of risk representation methods, how can designers ensure that participants truly understand the risks involved without being overly alarmed or desensitized?

05

Design Principles

"Transparent and ethical communication of risks is paramount in user research."

Understanding these methods is crucial for researchers designing studies that accurately assess user perceptions and behaviors related to security and privacy. Choosing the appropriate risk representation can significantly impact the validity and ethical considerations of the research findings.

06

What This Means for Your Design

When you ask people to test a design that might have security or privacy risks, there are many ways to tell them about those risks. This study looked at how researchers do it and found that some ways are better than others, and it's important to be ethical.

Paragraph starter

This research highlights the critical need for careful consideration of risk representation methods in user studies. As demonstrated by Distler et al. (2021), the choice of how to communicate potential security and privacy risks to participants can significantly influence study outcomes and ethical considerations. Therefore, when designing user studies, it is imperative to select and justify methods that are both clear and ethically sound.
