|Significance Statement||Paramedics play important roles in healthcare systems globally, yet little is known about their decision-making. There is evidence that individual differences in thinking style can predict differences in decisions and judgements (Phillips et al., 2016). Despite this, there have been few studies of thinking style in healthcare professionals, and all have measured only the intuition-effortful axis. Our study was the first to also measure open- and close-mindedness in paramedics, constructs implicated in understanding the relationship between intuition and effortful thinking (Stanovich, 2018). We used the CRT to measure participants’ willingness and ability to override their intuition and correlated their performance with self-reported thinking styles.
|Brief Description||Introduction: Paramedics play important roles in healthcare, yet little is known about their decision-making. There is evidence that thinking style can predict differences in decisions.
Method: Australian and New Zealand paramedics (n = 103; mean age: 38.7; mean 12 years experience; 44% female) and paramedic students (n = 101; mean age: 25.7; 59% female) completed a thinking style survey measuring active open-mindedness (AOT), close mindedness (CMT), preference for intuitive thinking (PIT) and preference for effortful thinking (PET). Participants also completed the 7-item Cognitive Reflection Test (CRT).
Results: Regression analysis found AOT, age and prior exposure to the CRT predicted cognitive reflection across all participants (R2 / R2 adjusted: 0.198 / 0.157; F(10, 192) = 4.752, p < 0.001). There were moderate correlations between CMT, age, and paramedic experience. There was no difference between paramedics and student performance on the CRT, though more students reported prior exposure to the items (33.7% vs 16.5%; Chi-square (2) = 8.02, p = 0.02). Those who reported prior exposure to the CRT scored significantly higher than those who had not (5.08 [1.44] vs 3.87 [1.70]; F(2, 201) = 14.34, p < 0.001).
Conclusion: These results showed decreased cognitive reflection as experience grows. Self-reported AOT was associated with cognitive reflection and indicates a role for open-mindedness in health professions to support decision-making.
Participants were Australian registered paramedics and New Zealand paramedics eligible for national registration. Student participants were undertaking accredited undergraduate paramedicine studies in Australian or New Zealand universities.
Participants were recruited through paramedicine and student social media groups, professional associations, employer groups, and universities offering paramedicine courses. The study was promoted on Facebook, Twitter and LinkedIn for six weeks in August and September 2020. Professional groups, major employers, and student paramedicine associations in Australia and New Zealand were all asked to assist with promoting the study. Based on estimated sample calculations, recruitment continued for six weeks or until a sample size of 250 was reached.
There were 328 surveys attempted and 237 completed (Table 1). Following removal of responses that took too long or failed the attention or random-responding checks, there were 204 valid responses available for analysis (Table 2).

Cognitive Reflection Test
The Cognitive Reflection Test (CRT; Frederick, 2005) is the most commonly used tool to assess intuitive versus effortful reasoning by measuring the ability to override an intuitively attractive but incorrect response and determine the correct answer. Since the original three-item version was first created in 2005, the CRT has been used and validated in a variety of settings and evolved over time (Patel et al., 2019). We used a 7-item version with reworked versions of the classic items plus additional non-numeric items (Table 3) (Newton et al., 2021).

Comprehensive Thinking Styles Questionnaire (CTSQ)
The Comprehensive Thinking Styles Questionnaire (CTSQ; Newton et al., 2021) measures preferences for both intuitive and effortful thinking as well as open- and close-mindedness. The instrument has potential to be used as a common measurement standard for assessing thinking styles. However, as a very new development it has not been used in a variety of domains.
The CTSQ has 24 items and four subscales (Table 4): Actively Open-minded Thinking (AOT), Close-Minded Thinking (CMT), Preference for Intuitive Thinking (PIT), and Preference for Effortful Thinking (PET). The items are scored on a 6-point Likert scale (ranging from 1 [strongly disagree] to 6 [strongly agree] with no neutral response option.
Comprehensive Thinking Scale Questionnaire: subscale definitions and items
Name of Scale Description Items
Actively Open-minded Thinking (AOT)*
Assesses the tendency to weigh new evidence against a preferred belief. 1. It is important to be loyal to your beliefs even when evidence is brought to bear against them.
2. Whether something feels true is more important than evidence.
3. Just because evidence conflicts with my current beliefs does not mean my beliefs are wrong.
4. There may be evidence that goes against what you believe but that does not mean you have to change your beliefs.
5. Even if there is concrete evidence against what you believe to be true, it is OK to maintain cherished beliefs.
6. Regardless of the topic, what you believe to be true is more important than evidence against your beliefs.
Close-minded Thinking (CMT) Assesses the conviction that an individual’s beliefs are correct, especially in contrast to alternatives. 7. I think there are many wrong ways, but only one right way, to almost anything.
8. In my experience, the truth is often black and white.
9. Truth is never relative.
10. The truth does not change.
11. Either something is true or it is false; there is nothing in-between.
12. There is no middle ground between what is true and what is false.
Preference for Intuitive Thinking (PIT) Assesses an individual’s preference to base decisions on gut feelings and trust in their own intuition when making decisions. 13. I like to rely on my intuitive impressions.
14. I believe in trusting my hunches.
15. When I make decisions, I tend to rely on my intuition.
16. Using my "gut-feelings" usually works well for me in figuring out problems in my life.
17. Intuition is the best guide in making decisions.
18. I often go by my instincts when deciding on a course of action.
Preference for Effortful Thinking (PET)* Assesses an individual’s tendency to engage in and enjoy effortful cognitive activity. 19. I’m not that good at figuring out complicated problems.
20. Thinking is not my idea of an enjoyable activity.
21. I try to avoid situations that require thinking in depth about something.
22. I am not a very analytical thinker.
23. Reasoning things out carefully is not one of my strong points.
24. Thinking hard and for a long time about something gives me little satisfaction.
The items are scored on a 6-point Likert scale (ranging from 1 (strongly disagree) to 6 (strongly agree) with no moderate response option. To compute a score for the measure, calculate the mean of each subscale.
* The Active Open-minded Thinking and Preference for Effortful Thinking subscales are reverse scored.
Survey materials were implemented in Qualtrics (Provo, UT), with recruitment and participation entirely internet-based. After viewing a participant information sheet and providing consent, participants completed the 7-item CRT with items in random order, followed by an additional question asking if the participant had seen the questions before. Participants then completed the CTSQ items in random order, followed by questions to check for attention and random responding. Finally, participants provided demographic information. Other than demographic questions to confirm their professional status and experience, none of the instructions or questions were specific to paramedic practice. The survey materials and data can be found at (URL).
The study protocol was considered and approved by the Australian National University Human Research Ethics Committee (2017/141). No inducements or payments were offered for participation. No personal data was collected for the study and the researchers were unable to identify individual responses.
In order to detect a correlation of at least 0.2 with 80% power at a significance level of 0.05 (two-tailed), 193 participants were required (Cohen, 1988). Correlation of 0.2 was selected based on previous research correlating CRT performance with CTSQ scales (Newton et al., 2021). The target of 250 allowed for a proportion of responses to be removed for inattention, incompleteness, or random responding.
Statistical analysis was conducted using ‘R’ version 4.0.5 (R Core Team, 2021). Frequency data are reported as count (percentage). Continuous variables are reported as mean (SD). Comparisons of categorical data were conducted using Chi-square test and continuous variables were compared using the relevant parametric test with P-values set at .05 two-tailed..
All data analysis was conducted on complete surveys after removing participants who responded inappropriately to the attention-check and random responding items. In addition, any survey that took longer than two standard deviations of the mean response time was removed.
The CRT was scored by one point for each correct answer (range: 0-7), with a higher score indicating a higher degree of cognitive reflection, or put another way, a greater ability to override an incorrect intuitive response.
To compute a score for the CTSQ, the mean was calculated for each subscale. The Active Open-Minded Thinking and Preference for Effortful Thinking subscales are reverse scored, so a higher score for all subscales indicates higher preference for that style.
