The project will explore how individual differences impact decision making and decision strategies. The goal is to design an intervention that helps less numerically-skilled individuals improve decision-making using meta-cognitive tools.

The project is financed by the National Science Center (NCN), project no. 2023/49/N/HS6/03244

Project objectives

Since the publication of the first test measuring numeracy, extensive research has revealed that numeracy is strongly linked with superior decision making. However, surveys conducted in multiple developed countries revealed that about one-third of respondents do not have the basic numeric skills to perform simple and everyday activities. Low numeracy is often linked to more disadvantageous outcomes in the financial, health, digital, and civic domains. Research on the psychological processes underlying numeracy sheds light on sources of difficulty for most reasoners.

Among many competing theories, Fuzzy Trace Theory (FTT) can potentially make the most diverse and robust predictions regarding the difference in performance between individuals with high and low numeracy. FTT argues that all individuals simultaneously encode verbatim representations of numbers alongside the categorical gist and ordinal gist of those same numerical inputs. Yet, individuals usually rely on their imprecise and more readily available gist representation to make decisions. FTT claims that highly numerate individuals, compared to less numerate individuals, can make superior decisions by extracting more accurate meaning (i.e., categorical or ordinal gist) from numbers due to their better understanding of qualitative patterns and relations between numbers. Empirical evidence from process tracing studies also supports this claim. Results indicate that highly numerate individuals, compared to less numerate individuals, spend significantly more time, sample more information, and switch less frequently between alternatives to create an affect-rich and accurate mental representation of the decision problems. Despite these theoretical predictions, a dearth of research has attempted to empirically test them as potential determinants for better decision making. The current study aims to fill this gap.

As a doctoral student at SWPS University in the Department of Psychology, I presented an idea that recurring irrationality is adaptively rational. In other words, I demonstrated that making a greater number of fast and suboptimal decisions is more rewarding than time and energy-intensive deliberate strategies in a resource constrained environment. I have also found that skilled decision makers (i.e., highly numerate individuals) are better at understanding task demands and are able to better adapt their decision strategy to align it with the resource constraint of a task. Since I am interested in decision strategies and individual differences, the Preludium grant will allow me to explore this relationship in more detail. For this purpose, I will design an intervention that addresses the decision strategies used by less skilled individuals and promotes improvement in better decision-making using meta-cognitive tools.

  • Methodology

    We propose that motivating or mandating less numerate individuals to increase deliberation will not only coax them to make a more accurate gist representation but also may allow them to utilize verbatim representation to make better decisions. We will investigate this research problem in one simulation study and six fully-incentivized pre-registered empirical studies grouped into three tasks.

    Task 1 & 2 can be divided into two separate studies, respectively: one with financial problems and another with medical decision problems. The necessary deliberation period required to observe the effect of enhanced deliberation on choice performance will be estimated from the simulation study for the financial problems. However, the deliberation period for the medical decision problems will be estimated from the pilot study. The metacognitive intervention in Task 1 is designed following the principle of nudge (i.e., changing the choice architecture) to constrain the decision maker to deliberate on each choice problem. Whereas, in Task 2, the metacognitive intervention was created by following the "boosting" principle (i.e., steering preference by increasing competence while preserving their freedom of choice) to motivate the decision maker to deliberate on each choice problem.

    In Task 3, unlike Task 1 & 2, we will combine the novel metacognitive interventions with already proven risk communication tools (i.e., graphical presentation of numeric information) to evaluate the effect of enhanced deliberation on choice performance between two contrasting interventions (i.e., nudging and boosting techniques).

    We hypothesize that deliberation would be positively correlated with the increment in choice performance across all three tasks. We posit that boosting intervention, due to the increment in overall competency, will be more effective compared to nudging intervention. Lastly, when numerical information is presented graphically, deliberation will significantly enhance the performance of less numerate individuals leading to no meaningful differences in performance between the high and low numeracy groups.

  • Practical application of results

    Taken together, the current project will provide an opportunity to test the effect of enhanced deliberation on choice performance. Furthermore, it will enable researchers to compare and contrast between the two dominant philosophical approaches toward intervention (i.e., nudging and boosting).

    Besides the theoretical implication of the current project, it also provides a potential framework that allows less numerate individuals to make better and more informed decisions.
