HN readers interested in scientific research fraud issues may like the blog Retraction Watch

http://retractionwatch.wordpress.com/

(which I'm pretty sure I learned about from another HN participant) with its worldwide reach in reporting on retractions of scientific journal articles. There is another source some HN participants may find of interest, a special issue of the journal Perspectives on Psychological Science on the topic of replicability of psychology research. The entire contents of the November 2012 issue of the journal

http://pps.sagepub.com/content/7/6.toc

are free to download for all members of the public, to spark discussion of research issues in psychology. There are some great reads by famous authors among those articles.

AFTER EDIT: Pertaining to the issue of submissions to Hacker News, one thing to look out for is mistaking the statements in a press release for statements actually supported by a peer-reviewed scientific journal article. Many journal articles that say a little are hyped by press releases that say a lot, which are then distorted by news articles by lazy reporters into announcements of "breakthroughs." We've seen a lot of submissions to HN like that over the years. The PhD Comics panel on "The Science News Cycle"

describes the process, with only just a little exaggeration for humorous effect.

Comments by earlier participants here on Hacker News alerted me to two particularly unreliable sources that I NEVER use as the basis of a new submission to HN.

PhysOrg appears to have been banned as a site to submit from by Reddit. ScienceDaily is just a press release recycling service, nothing more. Users here on HN think there are better sites to submit from.

Comments about PhysOrg:

"Yes Physorg definitely has some of the worst articles on the internet."

"Straight from the European Space Agency, cutting out the physorg blogspam:

http://www.spacetelescope.org/videos/heic1116a/ (video),

http://www.spacetelescope.org/static/archives/releases/scien... (paper).

"PhysOrg: just say no."

"The physorg article summary is wrong, I think."

http://news.ycombinator.com/item?id=4108857

"Phys.org is vacuous and often flat wrong."

Comments about ScienceDaily:

"Blogspam.

"Original article (to which ScienceDaily has added precisely nothing):

http://www.washington.edu/news/articles/abundance-of-rare-dn...

"Underlying paper in Science (paywalled):

http://www.sciencemag.org/content/early/2012/05/16/science.1...

"Brief writeup from Nature discussing this paper and a couple of others on similar topics:

"Everything I've ever seen on HN -- I don't know about Reddit -- from ScienceDaily has been a cut-and-paste copy of something else available from nearer the original source. In some cases ScienceDaily's copy is distinctly worse than the original because it lacks relevant links, enlightening pictures, etc.

" . . . . if you find something there and feel like sharing it, it's pretty much always best to take ten seconds to find the original source and submit that instead of ScienceDaily."

Comments about both PhysOrg and ScienceDaily:

"Why hasn't sciencedaily.com or physorg been banned from HN yet?"

"Original source:

http://www.nasa.gov/mission_pages/hinode/news/pole-asymmetry...

"What ScienceDaily has added to this: (1) They've removed one of the figures. (2) They've removed links to the Hinode and SOHO websites. (3) They've added lots of largely irrelevant links of their own, all of course to their own site(s).

"Please, everyone: stop linking to ScienceDaily and PhysOrg."

http://news.ycombinator.com/item?id=3867361

"Those sources don't have RSS feeds, and ScienceDaily and PhysOrg have a bad habit of not linking to such things."

"Added value in PhysOrg article: zero.

"Please, everyone, stop submitting links from PhysOrg and ScienceDaily. I have never ever ever seen anything on those sites that isn't either (1) bullshit or (2) a recycled press release with zero (or often negative) added value. (Sometimes it's both at once.) It only takes ten seconds' googling to find the original source."
