Dancer Test



Are you left-brained or right-brained? Supposedly, your brain lateralization determines how you view this animation.

Some people see her rotating clockwise. Others see her rotating counter-clockwise. Some see her unpredictably changing the direction of her rotation.

Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained.

I originally came across this animation here.

Anybody is free to do any suppositions.
But when everybody is doing the same supposition, it is taken almost as fact.

Why not make similar left/right brained supposition on the Necker cube?

The direction of rotation is both clock and counter clockwise.

I think there is no trick here .... or no optical illusion.

It is quite straight foward ... changing direction...

Watch the animation for about 30-50 secs ... with the idea the direction is changing... you can actually see the instant of changing the direction...

I wonder this has anything to do with left-right brain....

Shrini, not everyone sees a change of direction when they view the dancer. For example, I almost always see her rotating clockwise. My girlfriend, on the other hand, sees the dancer changing direction every few seconds.

Right .... I agree that people see the image differently. I am interested in knowing how do you relate these variations to compartmentalization of brain?

>>>Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained.

What about people who see neither? Like me - who see that the direction simply changes at about 10-20 secs.

I am interested to see how you make the connection?

Presumably, Shrini, the more often someone sees the dancer switch directions, the greater the balance of their left and right brain.

However, note that I wrote "supposedly" in the original statement and "presumably" in this most recent statement :-)

I don't know how valid the science is, but it's definitely interesting how different people see the dancer differently.

Why Spreadsheets Suck for Prioritizing

The Goal As a company executive, you want confidence that your product team (which includes all the people, from all departments, responsible for product success) has a sound basis for deciding which items are on the product roadmap. You also want confidence the team is prioritizing the items in a smart way. What Should We Prioritize? The items the team prioritizes could be features, user stories, epics, market problems, themes, or experiments. Melissa Perri  makes an excellent case for a " problem roadmap ", and, in general, I recommend focusing on the latter types of items. However, the topic of what types of items you should prioritize - and in what situations - is interesting and important but beyond the scope of this blog entry. A Sad but Familiar Story If there is significant controversy about priorities, then almost inevitably, a product manager or other member of the team decides to put together The Spreadsheet. I've done it. Some of the mos

Henry Ford's "Faster Horse" Quote

You may have heard the ( apocryphal ) Henry Ford quote: If I'd asked customers what they wanted, they would have said "a faster horse". Over at the On Product Management blog , Saeed gives his take on this infamous quote. He "hates" it, and gives some compelling reasons. Saeed is spot on in his explanations. Personally, I think the quote is great, but it's a matter of interpretation. The valid point of the quote is not that it's a bad idea to facilitate a conversation with your market to better understand it. The valid points are: You must ask the right questions to get valuable answers. You must interpret the answers thoughtfully - often outside their direct meaning - to glean reliable information. Asking questions is not always the best way to "listen" to your market. (E.g., sometimes pure observational studies are more reliable.) Nonetheless, I find the quote is helpful to combat "armchair product management" in the

Stop Validating and Start Falsifying

The product management and startup worlds are buzzing about the importance of "validation". In this entry, I'll explain how this idea originated and why it's leading organizations astray. Why Validate? In lean startup circles, you constantly hear about "validated learning" and "validating" product ideas: The assumption is that you have a great product idea and seek validation from customers before expending vast resources to build and bring it to market. Indeed, it makes sense to transcend conventional approaches to making product decisions . Intuition, sales anecdotes, feature requests from customers, backward industry thinking, and spreadsheets don't form the basis for sound product decisions. Incorporating lean startup concepts , and a more scientific approach to learning markets, is undoubtedly a sounder approach. Moreover, in larger organizations, sometimes further in the product life-cycle, everyone seems to have an opinio
