Choice Blindness In Males and Females

Lilly Tinsley and Vanessa Shadare

Choice Blindness

• Choice blindness is a form of inattentional blindness, a phenomenon in which people fail to notice unexpected stimuli in the world around them.

Hypotheses

• Null Hypothesis: There is no difference in choice blindness between males and females.

• Alternative Hypothesis: There is a difference in choice blindness between males and females.

Methods• 15 male and 15 females will be test

subjects.• Present two photos side by side and

ask the test subject to tell which person they find more attractive.

• Remove photos and re-present them with either their selection or or an alternative photo.

• Ask the subject to justify their choice.

Methods cont.

• Repeat previous steps ten times with each test subject using different pairs of faces.

• The same protocol will be followed with various scents instead of faces.

Analysis

• We are going to compare results among genders and senses.

• Sign tests and tests of heterogeneity will be employed.

Results

• After collecting data, we confirmed that our null hypothesis is correct– There is no difference in choice

blindness between males and females

– The amount of choice blindness exhibited by males and females is not significant, as determined by a sign test
