At dinner the other night my husband said, “How the heck could anyone be undecided two weeks before the election, when this campaign has been going on so long?”
I like to think that when I decide to buy something it’s because I’ve thought it through and it’s the best purchase. Logically and rationally. But I’ve read too much research on the unconscious and on decision making. So I know that people, including me, make decisions based on unconscious processing and that I don’t use logic as much as I’d like to think I do.
There’s this great research study that proves two concepts: 1) We don’t pay attention to very many attributes about a product, 2) We tend to choose the first item that appears on a product page of a web site.
Here’s the research citation:
Felfernig, A., G. Friedrich, B. Gula, M. Hitz, T. Kruggel, G. Leitner, R. Melcher, D. Riepan, S. Strauss, E. Teppan, and O. Vitouch. 2007.

Felfernig set up a website with tents. He had visitors to the site fill out a questionnaire about the type of camping they planned to do. Then the site recommended four tents based on ten different attributes, such as waterproofing, weight, air ventilation, etc. Based on the questionnaire you filled out, two of the four tents are rated as “best buys” for the attributes that are important to you. Which tent will you buy? Tent 1, 2, 3, or 4?
Even though there were ten attributes that the tents were compared on, participants in the study paid attention to only 2 or 3 of the attributes. And when it came time to pick a tent, the participants in the study didn’t even consider the attributes. They picked the first tent more than 2.5 times than any other. They chose the first one 200 times versus 60 for all the other choices combined.
But, just like me, the participants explained their choice, based on the logical decision they thought they were making. They would explain the choice of tent #1 by saying, “This tent is the most waterproof”, for example. They thought they were weighing all the attributes of all the tents, but in reality they were only looking at a few attributes and even those didn’t matter… all that mattered was which tent showed up first.
I’m going to see if I can pay attention to this the next time I go to buy something at a website where there are several choices on the page at once. Maybe if I notice I’m doing it I won’t be so prone to doing it?
