Rules:

1. Be civil


Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.


2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.


Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.


3. No bots, spam or self-promotion.


Only approved bots, which follow the guidelines for bots set by the instance, are allowed.


4. Post titles should be the same as the article used as source. Clickbait titles may be removed.


Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.

Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.


7. No duplicate posts.


If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.


8. Misinformation is prohibited.


Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.


9. No link shorteners or news aggregators.


All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link.

Summary

Homeland Security Secretary Kristi Noem has ordered lie detector tests for DHS staff to identify leaks that allegedly foiled immigration raids, including a failed Colorado operation targeting Venezuelan gang members.

The directive, leaked to Bloomberg, requires polygraph questions about unauthorized communications with media and nonprofits. Despite polygraphs' unreliability, DHS insists they are necessary for national security.

The crackdown follows frustration from Trump’s border czar Tom Homan over compromised raids and aligns with broader MAGA-era efforts to control government communication.

Honestly, that's all they're good for: creating paranoia/terror/nervousness in the subject. Go read the 'how to beat a polygraph' book. Knowledge is calming.

Also? It's not anything to do with symptoms showing stronger on baseline questions. The only big giveaway is breathing. I work in the medical field. Blood pressure, heart rate, bla bla bla... they all vary with frequencies and magnitudes that don't allow them to be filtered from responses that do signify anything. The only vital sign that has a low enough rate for changes to really be detected is how often you take a breath. If you control that, the game is over. A really observant tester watching a testee attempting (poorly) to mask breathing rate may notice something is off, but it's still a judgement call whether it's due to nervousness and the attempt to calm down, or actual deception.

The best way to 'pass' a polygraph is to be just nice/cute enough to get the tester to like you somewhat, and then control your breathing. The proper test has them talking to you for at least a half hour beforehand so they can 'get an idea' about you, so you have plenty of time to be friendly. Take advantage of that. There is some nice research out there about self-disclosures and their effect on being liked. If they see a pattern that could be you being nervous, could be you trying to deceive, being liked will tip them towards the kinder perception.
