Editing Conjunction fallacy (section)

==Joint versus separate evaluation==

In some experimental demonstrations, the conjoint option is evaluated separately from its basic option. In other words, one group of participants is asked to rank-order the likelihood that Linda is a bank teller, a high school teacher, and several other options, and another group is asked to rank-order whether Linda is a bank teller and active in the feminist movement versus the same set of options (without "Linda is a bank teller" as an option). In this type of demonstration, different groups of subjects still rank-order Linda as a bank teller and active in the feminist movement more highly than Linda as a bank teller.<ref name="tk83"/>

Separate evaluation experiments preceded the earliest joint evaluation experiments, and Kahneman and Tversky were surprised when the effect was observed even under joint evaluation.<ref name="tk2011-15">{{cite book |last=Kahneman |first=Daniel |title=Thinking, Fast and Slow |url=https://archive.org/details/thinkingfastslow0000kahn |url-access=registration |chapter=Linda: Less is More |year=2011 |publisher=Farrar, Straus and Giroux |location=New York |pages=[https://archive.org/details/thinkingfastslow0000kahn/page/156 156]–165 }}</ref>
