"The personal equation, in 19th- and early 20th-century science, referred to the idea that every individual observer had an inherent bias when it came to measurements and observations."
Those clever scientists decided the only way you could adjust for these biases was to take the measurements of several scientists, in order to find, for example, the correct location of that star you were all looking at.
That's my theory of journalism. Many stories, many sources, something closer to the truth. Where they overlap and intersect dwells something closer to the truth. I don't understand the religious attachment to the idea of journalistic objectivity. I don't believe that it exists. And I think it's silly to keep pretending that anyone can be objective. Really. Silly.
So, here you will also find my personal equations on whatever it is up i'm to writing about or listening to.
