People will listen to what they "want" to hear. People want acceptance from their peer/friends or relatives. People are gregarious. Nobody wants to be shun away. Why? Because of fear to be alone, fear of time and inevitable death, so they want to spend time and live the life with whom he can communicate. People want to be accepted by other in order their life to be meaningful. Now, in order to be accepted, people have to work within the society and family. You typically don't create rules in society. For most cases the rules are already there before you are born. And you can not change the rule all by yourself. It's too much work. And time is running against you. So the most pragmatic thing to get accepted by others is to go along to get along. That's how you don't have to spend lot of time to change everything. Instead you fit in. It's easy! Anything efficient, is also inbuilt in our system. Our entire learning is based on time efficiency. Look at those in Rescorla Wagner model. Look at Fibonacci sequence in the nature. Time is the constrain in the material/physical world. Time is the constraints of thermodynamics. As long as something physical, time constraints are always there. In this society people have no time or intention to discover everything all by themselves. They don't want to hear what's the reality. Honesty is, most of the time, time inconvenient. Honesty is painful. Honesty requires willing to accept inconvenience no matter what. Honesty is prime prerequisite to know the truth. And hence people are not interested in truth. There will be always some eyes that will not see, ears that will not hear, brain that will not perceive. Do you think, generally,  people is more ignorant than you. Think again. Its a matter of choice. The problem is people don't care about the real truth, they just care for convenience and time efficiency. In summary, people, generally speaking, don't care for the truth because its too time and effort consuming but unfortunately, in long run it's hurting themselves.

Additionally, people are highly protective in hiding the fact that they don't want to listen the truth. It's a paradox indeed. If they don't know that they don't want the truth then how can they hide it in first place? To answer to this question, I have to say that they consciously are not aware of that but they still know in their unconscious that they are selectively ignoring the truth. In rebellion their unconscious mind [as well as body], produced some defense mechanism that manifested as the behavior that points to the fact that they know something but are not sure but still trying to hide something. The typical manifestation include denial, sublimation, acting out, paranoia, spitting, getting busy in petty things, excessive talktativeness, busy talks in rumours, celebrity, fashions, footballs, action movies, sex, pornographies, violence and many other things depending on situation.

Like the truth detectors inside people's unconscious mind, everybody also has a internal time efficiency detector (ITED), and whenever other faculties of mind goes against the internal time efficiency detector, somehow truth signals are just ignored to give preference to ITED, and then to compensate, it creates variety of impulses. It needs an astute mind to see why and where from these impulses comes from. It's the missing link that is responsible for this amnesia. For example, Survive [pain and bodily sufferings are constant reminder of importance of survival] the thermodynamics in this material world > replicate or proliferate > sex> lust> romanticism> care and nurture> love. So in this point of view, survival and continuation becomes love. If you claim that I love, just for the sake of love but not sex, then it seems apparently illogical and you are in deep amnesia hidden inside your psychi. If you really mean that you just love for love, then I have to ask you the difficult question: What is the source of this love? Because, everything has a source. Everything is bound by a cause and effect. The effect you are seeing is love, but did you ever ponder, what is the cause or source or true purpose of love? Are you just hiding the original drive of love and sublimating this love by redirecting the same affection or feeling to an surrogate object or person?
