Difficulty: HardStrengthen

A comprehensive analysis of e-commerce behavior revealed that individuals utilizing virtual reality (VR) retail platforms make 40 percent more impulse purchases on average than those shopping exclusively via traditional mobile interfaces. From this observation, consumer psychologists deduce that the highly immersive nature of VR inherently degrades a shopper's self-regulation. Accordingly, they forecast that an industry-wide shift toward VR commerce will trigger a drastic escalation in impulsive buying across the general public.

Which one of the following, if true, most strengthens the psychologists' argument?

  1. Shoppers who exhibit strong baseline tendencies toward impulsive spending are no more likely to adopt VR retail platforms than are highly disciplined shoppers.Answer
  2. B
    The vast majority of individuals currently using VR retail platforms had a documented history of excessive impulse buying long before they acquired VR technology.
  3. C
    The absolute volume of impulse purchases processed through traditional mobile interfaces continues to dwarf the total volume processed through VR platforms.
  4. D
    Shoppers frequently report experiencing a more profound emotional attachment to brands they encounter within virtual reality environments.
  5. E
    Before the advent of VR technology, traditional mobile interfaces were already the fastest-growing sector for digital impulse purchases.

Answer

The option stating that shoppers with strong tendencies toward impulsive spending are no more likely to adopt VR platforms.
The argument concludes that VR technology itself causes an increase in impulsive buying by degrading self-regulation. This causal claim is based entirely on a correlation: VR users make more impulse purchases. The most significant vulnerability in this reasoning is self-selection bias—what if inherently impulsive people are simply more attracted to VR apps in the first place? The correct answer explicitly eliminates this alternative cause by stating that impulsive consumers are no more likely to adopt VR than highly disciplined consumers. By ruling out this major alternative explanation, the original claim that the VR environment is responsible for the impulsivity is significantly strengthened.

Step-by-Step Solution

1
Identify the argument's premises and main conclusion.
Premise: VR users have a 40 percent higher average rate of impulse purchases. Conclusion: VR's immersive nature inherently degrades self-regulation, causing a surge in impulse buying.
Deconstructing the argument is necessary to see that a causal claim is being drawn from correlative survey data.
2
Locate the primary logical gap or vulnerability.
The psychologists assume the VR environment is the cause, ignoring the possibility of self-selection bias (i.e., that naturally impulsive people simply prefer VR shopping).
Identifying the unstated assumption provides the blueprint for strengthening the argument.
3
Evaluate the choices to find the one that defends the causal claim.
The correct choice explicitly eliminates the self-selection alternative by stating impulsive buyers are no more likely to adopt VR than disciplined buyers.
Ruling out an alternative explanation is a definitive method for strengthening a correlational-causal argument on the LSAT.
