  In most cases, there’s a very big difference between what people say they need and what they actually need. This difference can be described in terms of attitude and behavior.
New Terms:
- Attitude: Attitude is how people think they behave. It signals what people want.
 - Behavior: Behavior is how people actually behave. It signals what people need.

                      The difference can be described in
terms of attitude and behavior, too.

                      Attitude is how people think they behave,

while behavior signals what they need.

                      This difference has been studied by social
psychologists since the beginning of

                      Results were so unbelievable that
researchers have been repeating

                      these studies over and over,
only to get the same exact outcome.

                      In a study conducted in
1937 by Stephen Corey,
                      0:33
                    
                    
                      students were asked about their
attitude towards cheating.

                      In other words, Corey wanted to know
what students said about their behavior.

                      A few weeks later, the same students
were given the opportunity to cheat.

                      Following a certain exam, they were
asked to grade their own performance.

                      There was close to zero correlation
between their attitude towards cheating
                      0:55
                    
                    
                      and actual cheating.
                      0:59
                    
                    
                      What they said about their behavior was
very different than their actual behavior.

                      Now you might think that research
from 1937 is not valued nowadays.

                      You might think that human
behavior changes over time.

                      The funny thing about human behavior
is that it doesn't change much.

                      In a study reported by the BBC News,
                      1:20
                    
                    
                      a UK-wide study was led
by Ron Cutler in 2012.
                      1:23
                    
                    
                      The researchers asked people coming out of
public bathrooms located in gas stations
                      1:28
                    
                    
                      whether or not they had washed their
hands after finishing their business.
                      1:33
                    
                    
                      99% of the interviewees said that
they did indeed wash their hands.
                      1:38
                    
                    
                      However, according to
electronic recording devices,
                      1:42
                    
                    
                      only 32% of men and 64% of women
actually did wash their hands.
                      1:46
                    
                    
                      While there are many possible
explanations for this difference,
                      1:51
                    
                    
                      the fact of the matter is that it was
proven again that there is a very big
                      1:56
                    
                    
                      inconsistency between what people say
they do and what they actually do.
                      2:00
                    
                    
                      This important difference
between what people want and
                      2:05
                    
                    
                      what they need is key to understand when
you work on developing a new product.
