Whoops, I forgot to mention the secret of the video I mentioned on Friday.
On Friday, I posted about a fascinating experiment demonstrating “inattentional blindness.” Go to this site, by the University of Illinois’s Visual Cognition Lab, and watch the video. As you watch, count the number of times the white-shirted team passes the basketball. Now that you’ve done it -- did you notice the guy in the gorilla suit who walks through the game? Crazy!












Do you have any more information on the implications of this study? It would be interesting to see what [possible] implications this has (if any).

yes what is the mystery here or the study? The gorilla was very obvious.. and ...??

The gorilla may seem obvious when you know to look for it, but about half the people miss it when they watch the video (they're too busy counting the number of times the ball is passed). This phenomenon is called "inattentional blindness". See this article for a longer explanation:

The gorilla experiment is mentioned about half-way down the page.

One thing that's not clear from the linked article - does the gorilla experiment work (in the sense of viewers not noticing the simian) only if viewers have been told beforehand to count the number of passes? Does it work just as well if viewers watch it with no particular purposes in mind?

During a diversity training workshop at Merrill Lynch a few years ago, the HBS professor facilitating the workshop showed this video. I missed the gorilla as did most of my senior ML colleagues. It highlighted that we see certain types of people as fit for the team (based on gender, race, MBTI-type, take your pick), or capable of moving the ball down the court, etc, and others we don't. Literally. It's a great study.

I could see the gorilla but I want to know if any of you could see the guerilla ;)

Too funny that you mentioned this on Friday. I was at the Ft. Worth Children's Museum THAT DAY and this video was in one of their exhibits! I noticed the gorilla while I was counting, and it actually threw off my count.

I would be wary of the implication that "we see certain types of people as fit for the team." If viewers are asked to count the number of passes by the *dark* shirted individuals, the gorilla will be impossible to miss.

I watched the video after you linked to it on Friday, and I didn't see the gorilla at all. I was totally focused on counting the number of passes. I found this totally fascinating. I'm still not sure I understand the implications of it.

The experiment works best if you don't tell people about the gorilla in the same paragraph as giving them the instruction/link.
Most people would at very least scan quickly the rest of the para, before heading off to visit the link. You have somewhat spoiled this great video.

Hi -- I didn't give away the gorilla the principle time I mentioned the video, on Friday. This was the "solution" post.
Yes, if you know about the gorilla, it's impossible to miss!

Gretchen,
I'm sorry, I missed the first post
so got the wrong impression. Apologies.
I try and read your blog every day
I only read about 7-8,
but sometimes life is too short
for even that :)

I love reading your site, and I was specially inspired by your 12 commandments so came up with a few for myself (of course I borrowed some of yours:-)
Here they are:
Be polite and fair
Let it go
Refuse to get offended
Enjoy the moment
Live in the present
Be the person you want to become
Treat people the way you want to be treated
Thanks a lot for inspiration:-)
X M
