Of course there is politicking. Any and every human institution has politicking. To believe otherwise one would have to be very naive about human institutions. And of course it good to be skeptical. You should always be skeptical of any claim, scientific or otherwise, claims about institutions, claims about anything that any human makes (dogs on the hand, you should always accept their claims at face value and without doubt )
Just remember though, there is often a baby in that bathwater, so be careful throwing it out!
