Kahneman & Tversky

#stu

Aim

to investigate the effect of availability Heuristics on system one processing (quick mathematical estimations)

Procedure

Two groups of high school students: estimated the result of multiplication with numbers in either ascending (1x2x3x4...)or descending (9x8x7x6...) order

Results

Mean estimated result was greater for the group with numbers in descending order (9x8x7...) than for the ascending condition

Conclusion

System one processing is prone to anchoring bias, as the first piece of information we receive affects our cognition.

Limitations

Mundane realism: not a task occurring often IRL, did not control for mathematical skills, which can affect the accuracy of estimated product
