With the non-abstract task, more people picked the correct cards.
This may be because instead of showing matching bias, the participants made their decisions instead based on relevant past experience, and thus were more likely to pick the correct card - this is referred to as ‘memory-cueing’ hypothesis
The more abstract and less relevant the task, the more likely that cognitive biases would be used to solve the problem.
Consequently, it could be inferred that matching bias is not as applicable to certain real life situations where the thinker has relevant past experience & knowledge.
IF Q ABOUT MODEL: Therefore, it can be suggested that a major assumption of the model - that system 1 is highly error prone - is not true in all situations.
