Dan Gilbert: The surprising science of happiness

Summary

             Dan Gilbert defended ,"There are two kinds of happiness, one is natural happiness,which means we get what we wanted so we are happy,the other one is synthesized happiness. Synthesized happiness is that we don't get what we wanted but we are happy in the end. According to the data,the levels of happiness of this two kinds are equal after 3 months.
            The reason why is we have impact bias.Most of us overuse our experience simulators so that we image different outcomes are more different than they in fact really are.That is to say,the other option is not as bad as we believe.In addition,we synthesize happiness,so we are happy. And, the option we preferred is not actually as good as we think. Synthesize happiness make us love what we choices more than when we haven't make the choices.It is changed by the time we make decisions.Follow the phenomenon, we infer that choices are friends of natural happiness but enemies of synthesize happiness.Once we have choices to switch our decision,we struggle that weather we should change or not.As a result,we don't like our decisions and deeply dissatisfied.
           In conclusion,we maximum the differences between two options.Our preferences push us so hard that we ignore our true values.Then, we can't be happy cause we can't always get what we want. Our irreversible choices bounded our longings and worries so we can be  happy.That is to say, if we don't long and worry that much,we could have achieved what we wanted to achieve.Of course,be happy.

What can listener learn from the talks?

           Sometimes,we makes ourselves unhappy by longing and worries too much.So we should know those true values first and then we make choices.The outcomes will always be right when we are not violate those true values.As a result,we don't have to be panic when things are not matching our expectations.Then,we will be happy.Take choosing departments of university for example.When I chose the department,I was in fears and pains.I don't know weather I chose the department right or not. What if I chose wrong one? Does that means I will be miserable for the rest of my life?After one year in university,I realize I can learn whatever I want, no matter what I major in.There are many ways to get it. The outcomes are not that difference.
           

Alessandro Acquisti: Why privacy matters

Summery 
           With the processing of technology, we post lots of information online. But, we are not aware of the effect of doing this. Alessandro Acquisti did some experiments to tell us how far the big data can do to our privacy and explain how they effect our lives. First of all, he randomly found a student in campus and took a photo of him.Then, he use the face identity system used by facebook and found the student's profile on facebook. Based on this information, 27% of subjects's first 5 digit of SSN can be found (in 4 attempts).It is like when you walk on the street people around you can know some information about you without asking.So, does that mean we can know a person better? Not exactly.The photos and information we posted are partly.People would judge us according to what we post.That would generate biases.
           Subconsciously,we know this fact. Alessandro Acquisti did another experiment and demonstrated that people are familiar with the situation without privacy.It doesn't mean they don't care. They just can do nothing about this.Current policy is not effective.However,Alessandro Acquisti still believe we will find  solutions to protect our privacy and enjoy the benefit of big data in the same time.
     
What can listener learn from this talk?
                We can know the data online is really big. We never know who will use this information to do what things.What is more,the process of  technology has been so fast that everything becomes possible. We should always be aware of what we post on line!
