Bounty for the best solution

Provide a bounty for the best solution

Bounties attract serious brainpower to the challenge.

Currency *
Who gets the Bounty *
A room full of sensors that can detect the slightest change in people's heartbeat, breathing, sweating, eye pupil dilation, etc.

Anyone in the room has their vitals displayed on a wall for everyone to see. The sensors track every person individually. The probability of truthfulness is included among the vitals.

  • In some conversations, trust might not be enough. Especially when people don't know each other well.
  • There are times where a person might want to volunteer to a lie detector to clear any doubts.
  • The ultimate way to show that you have nothing to hide.

Protect those people - now and in the future.

Michelle Christine Aug 21, 2021
I'm not 100% opposed to this. I absolutely hate that our world is built on secrets.

But I'm imperfect. Other people are imperfect. If I have the potential to be 100% perfect that's a nice idea, but not a starting point to assume that's the truth. From what I've been told, and taught, and have real-world reason to believe, people are always imperfect, even if they have really good intentions. If we expect people to be willing to tell the complete truth, it's first necessary to create an environment in which it's safe to do so, even if they're imperfect. Free from judgment. Free from disastrous consequences. Both now and in the future is probably the key point (the future is much harder to enforce). And I support the attempt to get there. If and only if we protect people from any negative interim consequences while we're "figuring it out" and after.

I also believe anyone and everyone should have complete unfiltered knowledge of any data collection and tracking of themselves, and who has access to that. It will propose a level of discomfort. A huge level of discomfort. But probably less than the alternative of a world shrouded in secrecy. There's a chance I'm wrong, in which case maybe, please shield me from that and allow me to live a good life. But I'm leaning towards a world of more transparency.

"Lie Detector" Tests through autonomic nervous system reactions to questions are inaccurate

salemandreus Aug 22, 2021
Despite their use, polygraphs and the biological indicators that they measure is known to be inaccurate which is why many states and countries do not allow them in court.

lawinfo.com identifies the problems this way:
"The accuracy of lie detector test results can vary depending on the person administering the test, the machine used, and the person taking the test. As such, polygraph results are generally not admissible in criminal cases."

Apa.org goes further into the psychological factors and the unproven causal nature in these tests: "The accuracy (i.e., validity) of polygraph testing has long been controversial. An underlying problem is theoretical: There is no evidence that any pattern of physiological reactions is unique to deception. An honest person may be nervous when answering truthfully and a dishonest person may be non-anxious.
A particular problem is that polygraph research has not separated placebo-like effects (the subject's belief in the efficacy of the procedure) from the actual relationship between deception and their physiological responses.

One reason that polygraph tests may appear to be accurate is that subjects who believe that the test works and that they can be detected may confess or will be very anxious when questioned. If this view is correct, the lie detector might be better called a fear detector. [...]
The cumulative research evidence suggests that [Control Question Tests] detect deception better than chance, but with significant error rates, both of misclassifying innocent subjects (false positives) and failing to detect guilty individuals (false negatives)."

These tests can also be beaten deliberately: "Evidence indicates that strategies used to "beat" polygraph examinations, so-called countermeasures, may be effective. Countermeasures include simple physical movements, psychological interventions (e.g., manipulating subjects' beliefs about the test), and the use of pharmacological agents that alter arousal patterns."
There are also plenty of online resources training people to beat lie detector tests.

Other factors known to affect a polygraph test are depression and anxiety as well as medications used to treat them.
An social psychologist and professor who specialised in polygraph tests for over 30 years, Leonard Saxe, says “Polygraph tests are not a valid technique for assessing truthfulness [despite sometimes being] required for jobs requiring a security clearance. [...] Assessing autonomic nervous system reactions to questions about one’s history should not be part of how individuals are selected for sensitive jobs.”
