<p>Every one likes different things, places, people, colors, flowers etc. 
I am interested to know how this mechanism is developed in individuals. If we suppose that it is started from home. </p>

<p><strong>Then why siblings have different interests.</strong> </p>

<p>If it is from society then living in same society still siblings have different interests. Like if two brothers are class fellows too and live in same people. still they will have different interests. </p>

Considering the classical discussion of *nature versus nurture*, we can assume here that part of the causality is nature (genes, epigenetics) and part is nurture (environment, upbringing). We are all born with a whole bunch of instincts, probably hundreds. Not all these instincts are in effect at a given time, and a baby of course is not going to be displaying those instincts which are not important to its current circumstances, needs, and capabilities. As a child grows, he or she will learn how the world functions and what causes what.
