Imagine, that you arrive somewhere, and it is offered a set of random subjects (which means an information choosen by an aleatory variable), which necessarily does not interest you, but by "coincidence", this random subject attracts your attention, then you choose to read the article.
After all you fall in love with such random subject, then someone comes to you asks "why you choosed such article and not such one?", Usually you will not know the answer, because since the variables were random you shall not prefer one to another, was a random choice too, then such person suggest for some reason another "article" since "he tries to presume that you think that he was the author of the previous one".
