1. La Inadmisibilidad Legal y la Falla Científica del Polígrafo.
La crítica más recurrente es que los detectores de mentiras son pseudociencia, midiendo solo el estrés fisiológico (como la respuesta galvánica de la piel) y no la mentira en sí. Por esta razón, sus resultados son generalmente inadmisibles como prueba en los tribunales, lo que subraya su falta de fundamento teórico y validez.
- Lie detectors dont work, its just pseudo-science. Fun for entertainment, but about as useful as astrology in real life.
- Polygraph, or lie detector, test results are generally not admissible in court due to concerns about their reliability and scientific validity.
- As a psych major, i got to tinker with lie detector technology. Its actually measuring physiological signs of stress like galvanic skin response. The correlation between stress and lying exists but its far from exact.
- An fbi agent under oath in 1997 admitted that lie detectors are without any theoretical foundation and have absolutely no validity.
2. Métodos para Engañar la Máquina y la Paradoja del Mentiroso.
Se menciona que los polígrafos son fáciles de manipular. Los sociópatas y mentirosos patológicos a menudo pasan las pruebas porque no experimentan estrés al mentir. Irónicamente, las personas ansiosas o honestas pueden fallar debido a los nervios. Se citan técnicas populares para crear una línea base falsa, como infligirse dolor o realizar contracciones musculares durante las preguntas de control.
- The funniest thing about lie detectors is how shit they are at detecting lies when the lier is totally unbothered by lying. Sociopaths pass lie detectors all the time because they arent stressed at all.
- Aparently you can beat a lie detector by clenching your asshole whenever you tell the truth critically during the control questions, too, which stimulates similar responses to lying.
- The worst part he actually believes that polygraphs work like everyone smart knows they only do signs of lying like sweating heart beat and so on so if you know how to lie you will be save but if you are actually telling the truth and just a bit anxious you run the risk of being a false positive.
- You only have to look at bongino to know that hed probably fry the lie detector if you were to hook him up to it.
3. Uso Político y Mediático: De la Venganza a la Propaganda.
A pesar de su falta de fiabilidad, el detector de mentiras se propone frecuentemente como una herramienta de rendición de cuentas para políticos y funcionarios, a menudo con la fantasía de aplicar descargas eléctricas a los mentirosos. También se destaca su uso como entretenimiento en programas de televisión y entrevistas a celebridades, como las populares series de Vanity Fair.
- We need a republican lie detector that gives a hundred-volt shock when lies are detected. To be worn permanently.
- Id love to take a lie detector test for fun and not at all for anything i may or may not have done in the past. But for fun. Dateline.
- Elected officials should be fitted with shock collars that have built in polygraph machines. They should get 10,00 volts every time a lie is detected.
- Jennifer lawrence and robert pattinson take lie detector test with vanity fair! filmed in nyc - 1st november 2025.
4. La Búsqueda de la Detección de Mentiras Avanzada.
El escepticismo sobre los polígrafos tradicionales ha llevado a la especulación sobre tecnologías futuras o alternativas. Se mencionan conceptos de detectores de mentiras cuánticos, el uso de análisis de voz, o la idea de "detectores de mentiras humanos" basados en la lectura de microexpresiones o el lenguaje corporal, aunque estos últimos también son vistos con cautela.
- Physicists just built a quantum lie detector. It works. Via science physics quantumphysics quantummechanics computersciences.
- I know they are able to pass lie detectors often but i have not seen where they can likewise control their voice data. At least not without chemical assistance and a drug screen could take care of that.
- I think im a human lie detector sometimes. Like what you said doesnt match up with what you said on this day and time and now im putting two and two together.
- Can one of those people with unlimited money pay to design an actual lie detector? this world needs them.
