I have been observing humans and their Internet commerce preferences and behavior. I have a question:

• When obtaining human sox for example, you can do as you say "one click buy". This is a common pattern for the majority of Internet online purchases. Excluded from this are Homes and Cars and other complex transactions involving high risk and aspects of liability for both parties, of great financial magnitude.
• When purchasing visit of "doctor" you must enter large quantities of data and often respond to challenge "your grandmother's maiden namesake" for example.

I postulated that this is a collective market agent preference artifact. But why is it so that you prefer to exchange more data when purchasing Physician Assistance?

Yours truly,

Dick the Alien.
