Just curious. 104 replies and 15 images omitted. Click here to view. >> Conspiracy theories are a conspiracy. Actually, seriously, there's FOIA documents and Church Committee minutes recording incidents of COINTELPRO operations literally brainstorming conspiracy theories and tossing a ton of them into the media to muddy the waters as to what is really going on. They also have political advantages, if you spin the story proper - make some politician look as though he's in on the globalist conspiracy and the like. I suspect a lot of these conspiracy theories are astroturf, rather than grass roots. Granted, it's almost impossible to tell which is which, as intended, and there's just enough that turn out to be real to lend credit to any one of them, almost regardless of how outrageous. But when you see a ton of different conspiracy theories suddenly surrounding a single event before it's even had time to circulate, it gets rather suspicious. There's plenty of evidence (also uncovered by FOIA) that points to the fact that the operation never really ended. Still not as fun as the incidents of the FBI and CIA producing fake porn to discredit targets though (tfw you missed out on being a government funded porn star.) >> File: mqdefault (2).jpg (15 KB, 320x180) 15 KB JPG >>8703762 This...

A depressed patient doesn't need to be aware of his depression before he gets better. It may just improve with time since issues like this are often episodic. I don't think any psychologist worth their salt would tell a patient that they need to just "will" their way out of being sick either. Being generous with this argument, you could say that a patient may need to relearn how to cope with life in healthier ways. This is just attempting to recondition your brain. It's not something that necessitates an understanding of the issue from the patient's POV anymore than a recruit undergoing training needs to understand the logic behind everything they're being told to do. In a lot of cases the idea is that they don't understand so they're more malleable and easier to brainwash into following orders without thought as to whether or not they really should.

95% of the students from my uni write the conclusion paper (don't know how you call it in english) just because they must do it to finish the course, doing as little work as possible.

I still have two years to conclude my chem degree and I plan to invest a lot of time on it and really try to do a good job. Then I ask /sci/, is it possible to write an useful conclusion paper? I don't want to get a nobel prize for it but would be nice to do something other people could use.

Graduate student Harriet Hungate took Kaczynski’s topology class. He impressed her.

“He was this young guy, tall and good looking, and had all the outward manifestations of someone who would be very sociable,” she said.

Hungate needed someone to talk to. She was in crisis, thinking of dropping out, “hanging in there by the skin of my teeth.”

She went to Kaczynski’s office for a conference. She asked questions about the course, but then her emotions took over. She spilled out her fears and doubts, looking to her professor for warmth and reassurance.

His response chilled her. Kaczynski didn’t acknowledge she had spoken.

“There was no reaction at all,” Hungate said. “Usually there’s a person in there who responds to what is said, but I looked in his eyes, and I saw no person there.”

He's anti-technology and anti-power he believed an anti-left stance was just a means to an end. There is nothing stopping him from being anti-right too.

In the end he's anarcho-primitivist and that is classically a leftist ideology. His anti-leftist stance was a reaction to leading leftist ideologies combined with his belief that technology and power were the means of leading leftist ideals. A hippy commune of anarcho-primitivist is more likely to identify as left since taking a violent reactionary stance is fairly uncommon.

Kaczynski math-compiling-fag here,

I wish to state for the record that this thread has finally led me to fully investigate the context of a humorous footnote, made in some other paper. I had been wondering about it for a while.

-an image (pic related) has floated around the internet, and apparently now that I look is on the hated Reddit, a subject of discussion there. The point of the image is that someone is actually citing Kaczynski's work and is drily minimizing/calling attention to his other work.

-googling the right phrases with the key FOOTNOTE returns a blurb at now-irrelevant (blessedly, thanks to Trump's win) conservative magazine National Review. Political commentator and popsci math book author (but really, they're pretty good) John Derbyshire used to be a regular contributor there, until he was forced out due to having written a sensible yet politically incorrect piece of advice.

http://www.nationalreview.com/corner/140222/unexpected-encounter-john-derbyshire

So there turn out to be two associated papers: the thing citing Kaczynski, and Kaczynski's older paper (note) itself. The big important point about this older Kaczynski paper is that it is NOT mentioned at the popular Kaczynski mathematical bibliography, which is HERE

http://homepages.rpi.edu/~bulloj/tjk/tjk.html

The point being that there are other professional publications due to Kaczynski which I was previously unaware of! Moreover, it looks like my old college library has the stuff on physical file (there are kike paywalls / uniwalls associated with the online content), so I see a field trip coming up: get this other work of Kaczynski.

The paper CITING Kaczynski, source of the minor meme, is here:
