## 4 The Results of Hypothesis Testing  
### Descriptive Analysis  
The latent variables in our study, presented in Figure 1, include Extraversion Characteristics (EXCs), Agreeableness Features (AGFs), Conscientiousness Attributes (COAs), Neuroticism Factors (NEFs), Openness Aspects (OPAs), Quality of Decision (QOD), Confidence in Decision (CID), Self-Assessed Knowledge (SAK), and Test-Assessed Knowledge (TAK).  
Each latent variable is assessed through specific indicators. Table 1 includes seven of these latent variables, with QOD and CID detailed later due to their unique role as outcome variables in the structural model.

Table 1: Construct, means, standard deviations, and loadings.  
The Big Five Inventory (BFI) was used to measure personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness). For each personality construct, the indicators are represented as follows:  
* EXC1, EXC2, and EXC3 for Extraversion Characteristics;
* AGF1, AGF2, and AGF3 for Agreeableness Features;
* COA1, COA2, and COA3 for Conscientiousness Attributes;
* NEF1 and NEF2 for Neuroticism Factors;
* OPA1, OPA2, and OPA3 for Openness Aspects.  
The Big Five Inventory (BFI) was used to measure personality constructs. Each latent variable is measured via observed variables corresponding to individual items within the BFI. Detailed descriptions of these items are provided in the Supplementary Materials.  
The mean, standard deviations, and loadings of the construct for each indicator under consideration are shown in Table 1. The mean values exhibit a range from 1.69 for the indicator EXC1 to 3.80 for OPA3. The highest mean values are evident in the Openness Aspects (OPA) construct, while the lowest is observed in the Extraversion Characteristics (EXC) construct. The means for most of the indicators are dispersed across a spectrum that leans towards the higher end of the scale, particularly for the OPA and TAK constructs.  
As for the standard deviations, these values oscillate between 0.688 for EXC2 and 1.042 for SAK2. Indicators within the Extraversion Characteristics (EXCs) construct have the least variability, as indicated by their lower standard deviations. Indicators belonging to the Self-Assessed Knowledge (SAK) construct display the highest variability, denoting a broader range of responses.
