Effectiveness and Perception of Dark Patterns IT & Society | SS 2023 | Exercise 10 18 What are Dark Patterns? Dark Patterns are subtle design features embedded in websites that prey on human psychology to steer consumers into making decisions that, if fully informed or under optimal conditions, they might not make and which go beyond acceptable marketing practices. How do Dark Patterns differ from Nudges? Dark patterns are ‘dark nudges’ with the intent to steer customers towards disadvantageous decisions (e.g., impulse purchase or accepting privacy policies), while nudges could be used in a positive sense (e.g., health or energy savings). Examples: ● Forced Continuity ● Sneak in to basket ● Countdown-Timer ● etc. (see lecture for more) Source: [1] Sin, R., Harris, T., Nilsson, S., & Beck, T. (2022). Dark patterns in online shopping: do they work and can nudges help mitigate impulse buying?. Behavioural Public Policy, 1-27. IT & Society | SS 2023 | Exercise 10 Q&A: #1635234 19 How do Dark Patterns work? ● ● ● They evoke System 1 thinking rather than System 2 thinking They do this by exploiting cognitive biases like scarcity bias or social proof This has a strong influence on impulse buying decisions Source: [1] Sin, R., Harris, T., Nilsson, S., & Beck, T. (2022). Dark patterns in online shopping: do they work and can nudges help mitigate impulse buying?. Behavioural Public Policy, 1-27. IT & Society | SS 2023 | Exercise 10 Q&A: #1635234 20 System 1 vs. System 2 thinking System 1 thinking is a near-instantaneous process; it happens automatically, intuitively, and with little effort. It’s driven by instinct and our experiences. System 2 thinking is slower and requires more effort. It is conscious and logical.

(2022) Four Hypotheses were tested: 1) Consumers exposed to social proof dark pattern (a customer testimonial) will have significantly higher buying impulse than the control group 2) Consumers exposed to supply-related scarcity messaging (‘Only 5 left in stock – Order soon’) will have significantly higher buying impulse than the control group 3) Consumers exposed to demand-related scarcity messaging (‘Item in high demand – Order soon’) will have significantly higher buying impulse than the control group 4) Consumers exposed to supply-related scarcity messaging will have significantly lower buying impulse than those exposed to the demand-related scarcity messaging.

(2022) Setup: ● Survey participants were presented with a hypothetical online shopping experience involving Red Yeast Rice. ● Each participant was shown a scientific information sheet about the product, then actual product information from Amazon and lastly one of three dark patterns (High-Demand, Positive Testimonials, Limited-Quantity). ● After each piece of information they were asked about their urge to purchase.

IT & Society | SS 2023 | Exercise 10 Q&A: #1635234 25 Are more aggressive Dark Patterns more effective? Study by Luguri & Strahilevitz (2021) – Study 1 Setup: ● A representative sample was surveyed about demographic information, living situation, and attitude and opinion on data privacy (this took up most of their time). ● They were then told that, based on previous responses, the system had identified them as a person with a heightened concern about privacy. Therefore, they were automatically offered an identity theft protection plan for which they would receive a 6-month free trial and then be billed monthly for the service. ● The survey participants were then exposed to different dark patterns while evaluating this offer. ● After accepting or declining the offer participants were surveyed about their mood and whether they want to engage in follow-up surveys.

IT & Society | SS 2023 | Exercise 10 Q&A: #1635234 26 Are more aggressive Dark Patterns more effective? Study by Luguri & Strahilevitz (2021) – Study 1 Setup (continued): ● Control group: Just “Accept” and “Decline” options. ● Mild dark patterns: “Accept and continue (recommended)”, which was selected by default or “Other options”, if they chose “Other options” the participant had to select why they do not want this offer (confirmshaming answer options) or could choose “On second thought, please sign me up for 6 months of free credit history monitoring and data protection services.” ● Aggressive dark patterns: Same structure as for mild dark patterns, but after they chose an option for declining the offer, the participants were presented additional information about identity theft which could not be skipped for ten seconds. At the end, they were presented a trick questions about whether they want to accept the offer or not. Source: [1] Luguri, J., & Strahilevitz, L. J. (2021). Shining a light on dark patterns.

Study by Luguri & Strahilevitz (2021) – Study 2 Setup: ● Similar to study 1; difference: different dark patterns were included during initial offer (Hidden information, Social Proof, Scarcity, Confirmshaming). ● Additionally, different options for ‘Accept or Decline’ conditions (control, default, recommendation, and ‘More Options’). ● Same follow-up scenarios for the ‘More Options’ condition as in study 1.

How do people perceive Dark Patterns? Study by Luguri & Strahilevitz (2021) ● ● ● Aggressive dark patterns led to a significant higher dropout rate (9 vs. 65 participants) in the second study. Reasons? - The more participants were exposed to dark patterns, the more likely they were to feel forced into accepting the offer. Control group had significant more interest to participate in follow-up surveys compared to mild and aggressive dark patterns. However, there was no difference between mild and aggressive dark patterns. Source: [1] Luguri, J., & Strahilevitz, L. J. (2021). Shining a light on dark patterns.

Some dark patterns are more effective than others. Dark patterns do not, opposing to our own perception, lead to backlash if applied moderately. Is regulation required?

Making a realistic deepfake from scratch – alongside many hours needed for model training – requires lots of hours of human assistance and technology expertise. However, once the model has been trained for a particular face, a deepfake can be generated in the matter of minutes.

Threats1 Believability: The brain’s visual system, despite being largely robust in natural settings, can be targeted for misperception. If we see something with our own eyes, we believe it to exist or to be true - even if it is unlikely. Accessibility: Creating deepfakes is becoming easier and is allowing anyone to create them without significant investments. Areas of threat: - Reputation - Politics - Economics Source: [1] Kietzmann, J., Lee, L. W., McCarthy, I. P., & Kietzmann, T. C. (2020). Deepfakes: Trick or treat?.

Possible solutions to minimise the threat: - Starving the model of data by controlling your media presence; - Deepfake detection; - Authenticating any genuine media; - Raising public awareness. There are still little economic incentives for companies to provide a thorough deepfake detection solution. Source: [1] Exploring Deepfakes. by Bryan Lyon, Matt Tora. Released March 2023.

Some dark patterns are more effective than others. Dark patterns do not, opposing to our own perception, lead to backlash if applied moderately. The legal regulations on dark patterns are complicated – they are covered by different Directives and Acts, depending on the exact case. The goal of The European Commission is to fill the legal gaps on dark patterns. Technologies being developed with the intention of misleading people are only beginning to take off – deepfakes being one of the primary examples. General public is of the opinion that something should be done regarding misleading information online and raise their concerns on this topic. IT & Society | SS 2023 | Exercise 10 Q&A: #1635234 60
