Testing the Endowment Effect

Testing the Endowment Effect | Science Fair Projects | STEM Projects
Ever wonder why you might value something more if you own it? This experiment will help you find out! You'll divide participants into two groups and give each group a mug. Then, you'll ask them to assess the value of the mug. Finally, you'll compare the results to see if the endowment effect is true.

Hypothesis

The hypothesis is that a person will value a possession more if they own it.

Method & Materials

You will divide participants into two groups, give each group a mug, and ask them to assess the value of the mug.
You will need participants (at least 8), items for each participant (all the same), and a data sheet.

Results

The results of this experiment showed that the endowment effect is true: people value possessions more if they own them. One observation that stood out was that people were willing to pay more for the mug they owned than for an equivalent mug they did not own.

Why do this project?

This science project is interesting because it helps us understand why people value possessions more if they own them.

Also Consider

Variations to consider include using different items for the experiment, or having participants assess the value of the items before and after they own them.
