Q

INTRO WHAT’S COGNITIVE BIASES

A

Cognitive biases are errors in thinking that affect our ways of thinking, problem-solving, and decision-making. It occurs when people are processing and interpreting information in the world around them and affects their decisions and judgments. Cognitive biases are a type of heuristic, which are mental shortcuts created from prior knowledge. Because humans are cognitive misers, we tend to create cognitive shortcuts to decrease our cognitive load. We value our cognitive resources and use those mental shortcuts to save time. One example of a cognitive bias is the anchoring bias. It is when one relies too heavily on the first piece of information when given to them.

Q

WHATS ANCHORING BIAS

A

Anchoring bias is a mental shortcut that can influence our decisions in a significant way. It describes our tendency to rely too heavily on the first piece of information we encounter when making a judgment. This “anchor” information serves as a reference point, and we tend to adjust our thinking around it, even if it’s not necessarily relevant or accurate.

S1 PROCEDURE

A

High school students were split into two conditions: “ascending condition” and “descending condition”. The ascending condition was asked to estimate the value of 1 X 2 X 3 X 4 X 5 X 6 X 7 X 8 and the descending condition was asked to estimate the value of 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1.

A

PPTS given the question
“imagine the USA preparing for an outbreak of a disease that’s expected to kill 600 ppl, two alternative programs are proposed to combat this”

GROUP 1:
A: 200 saved
B: 1/3 chance 600 saved 2/3 nobody saved

S2 FINDINGS

A

OPT A: 72% ppts chosen
OPT B: 28%
OPT C: 22%
OPT D: 78%

Logically the question given to each group was equivalent but only difference was how it was FRAMED

Q

S2 CONCLUSION

A

The only diff was the FRAMING of the question, “will die” “will be saved” This shows that the framing effect took place and influenced ppts thinking and causes a bias in their decision making.
