  • The Supreme Court of Canada ruled Thursday that evidence obtained through hypnosis should not be used in criminal cases because testimony based on such evidence is not "sufficiently reliable" in a court of law.
  • evidence obtained through hypnosis has been used byCanadian courtsfor nearly 30 years.
  • the technique of hypnosis and its impact on human memory are not understood well enough for post-hypnosis testimony to be sufficiently reliable in a court of law

  • hypnosis can, in certain circumstances, result in the distortion of memory.
  • Initially, the neighbour told police she saw Trochym on the afternoon of Thursday, Oct. 15, 1992,but after she underwent hypnosis at the request of police, she remembered she sawthe accusedleave on Wednesday afternoon.
  • In its ruling, the court said the dangers posed by problems with the evidence could deprive an accused of a fair trial.
  • But dissenting judges, in their reasons, expressed concern about the majority ruling in which hypnosis is described as a "novel science" and "hypnotically refreshed memories" are now consideredinadmissible as evidence. "This ignores the fact that the technique has been used in Canada for almost 30 years, and has been employed in Canadian criminal investigations to assist in memory retrieval of both Crown and defence witnesses for a similar amount of time," they wrote. "Hypnosis is not new science, nor is its use in forensic investigation new."

  • dubious psychological techniques were used to put a teenager behind bars for life. These flawed ideas may still be at play in other criminal cases.
  • but in the '70s, hypnosis seemed like a powerful tool to use in criminal investigations. So when police found Jeffrey Boyajian's body slumped against a dumpster in 1979, they relied on hypnosis to find suspects.
  • This idea that you can pluck a memory from your mind and then use hypnosis to zoom in on it like a sports replay runs counter to what researchers now know about how the mind works.

  • Memory does not work like that. It does not work like a video camera or a DVR.
  • hypnosis-induced testimony is problematic.
  • If your goal is to get people to get to their - to the actual memory for the actual scene in question, if they didn't encode it at the time, it's probably not there to be retrieved.
  • The judge felt Clay should not be treated as a child. This decision was based in part on the outcome of a Rorschach test where a person is asked to look at an inkblot and describe what he sees.
  • They're not listening to the truth. They don't accept the truth. And when I was growing up, they had this notions about kids should be seen and not heard. And I was being seen, but I was not being heard.
  • the Justice Department's manual for federal prosecutors says that, in rare cases, forensic hypnosis can aid investigations.
  • according to the National Registry of Exonerations, there have been at least 10 cases of wrongful conviction that involve hypnosis. Clay would still be in prison today, but a few years ago, he was granted parole and Lisa Kavanaugh helped get his conviction thrown out.
  • Fred Clay's codefendant, James Watson, is still serving out his sentence. Watson's guilty verdict was based in part on the same problematic eyewitness testimonies that put Clay in prison. Watson is now seeking to have his conviction overturned. Shankar Vedantam, NPR News.

What is hypnosis and how might it work? - 0 views

  • Hypnosis can be seen as ‘a waking state of awareness, (or consciousness), in which a person’s attention is detached from his or her immediate environment and is absorbed by inner experiences such as feelings, cognition and imagery’.1 Hypnotic induction involves focusing of attention and imaginative involvement to the point where what is being imagined feels real. By the use and acceptance of suggestions, the clinician and patient construct a hypnotic reality.
  • Everyday ‘trance’ states are part of our common human experience, such as getting lost in a good book, driving down a familiar stretch of road with no conscious recollection, when in prayer or meditation, or when undertaking a monotonous or a creative activity. Our conscious awareness of our surroundings versus an inner awareness is on a continuum, so that, when in these states, one’s focus is predominantly internal, but one does not necessarily lose all outer awareness.
  • Hypnosis could be seen as a meditative state, which one can learn to access consciously and deliberately, for a therapeutic purpose. Suggestions are then given either verbally or using imagery, directed at the desired outcome. This might be to allay anxiety by accessing calmness and relaxation, help manage side effects of medications, or help ease pain or other symptoms. Depending on the suggestions given, hypnosis is usually a relaxing experience, which can be very useful with a patient who is tense or anxious. However, the main usefulness of the hypnotic state is the increased effectiveness of suggestion and access to mind/body links or unconscious processing. Hypnosis can not only be used to reduce emotional distress but also may have a direct effect on the patient’s experience of pain.2

  • What the Bay Area-based cartoonist recognizes, he says, is the careful art behind Trump’s rhetorical techniques.
  • Adams believes Trump will win because he’s “a master persuader.”
  • His stated credentials in this arena, says Adams — who holds an MBA from UC Berkeley — largely involve being a certified hypnotist and, as a writer and business author, an eternal student in the techniques of persuasive rhetoric.
  • ...18 more annotations...
  • “The most important thing when you study hypnosis is that you learn that humans are irrational,
  • what Trump is doing? He is acknowledging the suffering of some, Adams says, and then appealing emotionally to that.
  • 2. Knowing that people are irrational, Trump aims to appeal on an emotional level.
  • Having nothing to lose essentially then increases his chance of winning, because it opens up his field of rhetorical play.
  • Within that context, here is what Candidate Trump is doing to win campaign hearts and minds
  • 1. Trump knows people are basically irrational.
  • he bolsters that approach, Adams says, by “exploiting the business model” like an entrepreneur. In this model, which “the news industry doesn’t have the ability to change … the media doesn’t really have the option of ignoring the most interesting story,” says Adams, contending that Trump “can always be the most interesting story if he has nothing to fear and nothing to lose.”
  • “The evidence is that Trump completely ignores reality and rational thinking in favor of emotional appeal,” Adams writes. “Sure, much of what Trump says makes sense to his supporters, but I assure you that is coincidence. Trump says whatever gets him the result he wants. He understands humans as 90-percent irrational and acts accordingly.”
  • 3. By running on emotion, facts don’t matter.
  • “There are plenty of important facts Trump does not know. But the reason he doesn’t know those facts is – in part – because he knows facts don’t matter. They never have and they never will. So he ignores them.
  • 4. If facts don’t matter, you can’t really be “wrong.”
  • “If you understand persuasion, Trump is pitch-perfect most of the time. He ignores unnecessary rational thought and objective data and incessantly hammers on what matters (emotions).”
  • “Did Trump’s involvement in the birther thing confuse you?” Adams goes on to ask. “Were you wondering how Trump could believe Obama was not a citizen? The answer is that Trump never believed anything about Obama’s place of birth. The facts were irrelevant, so he ignored them while finding a place in the hearts of conservatives.
  • 5. With fewer facts in play, it’s easier to bend reality.
  • Among the persuasive techniques that Trump uses to help bend reality, Adams says, are repetition of phrases; “thinking past the sale” so the initial part of his premise is stated as a given; and knowing the appeal of the simplest answer, which relates to the concept of Occam’s razor.
  • 6. To bend reality, Trump is a master of identity politics — and identity is the strongest persuader.
  • “The best Trump linguistic kill shots,” Adams writes,”have the following qualities: 1. Fresh word that is not generally used in politics; 2. Relates to the physicality of the subject (so you are always reminded).”
  • : “Identity is always the strongest level of persuasion. The only way to beat it is with dirty tricks or a stronger identity play. … [And] Trump is well on his way to owning the identities of American, Alpha Males, and Women Who Like Alpha Males. Clinton is well on her way to owning the identities of angry women, beta males, immigrants, and disenfranchised minorities.

Can you trust your earliest childhood memories? - BBC Future - 1 views

  • The moments we remember from the first years of our lives are often our most treasured because we have carried them longest. The chances are, they are also completely made up.
  • Around four out of every 10 of us have fabricated our first memory, according to researchers. This is thought to be because our brains do not develop the ability to store autobiographical memories at least until we reach two years old.
  • Yet a surprising number of us have some flicker of memory from before that age
  • ...23 more annotations...
  • Experts have managed to turn people off all sorts of foods by convincing them it had made them ill when they were a child
  • “People have a life story, particularly as they get older and for some people it needs to stretch back to the very early stage of life,”
  • The prevailing account of how we come to believe and remember things is based around the concept of source monitoring. “Every time a thought comes to mind we have to make a decision – have we experienced it [an event], imagined it or have we talked about it with other people,” says Kimberley Wade
  • Most of the time we make that decision correctly and can identify where these mental experiences come from, but sometimes we get it wrong.
  • Wade admits she has spent a lot of time recalling an event that was actually something her brother experienced rather than herself, but despite this, it is rich in detail and provokes emotion
  • Memory researchers have shown it is possible to induce fictional autobiographical memories in volunteers, including accounts of getting lost in a shopping mall and even having tea with a member of the Royal Family
  • Based on my research, everybody is capable of forming complex false memories, given the right circumstances – Julia Shaw
  • In some situations, such as after looking at pictures or a video, children are more susceptible to forming false memories than adults. People with certain personality types are also thought to be more prone.
  • But carrying around false memories from your childhood could be having a far greater impact on you than you may realise too. The events, emotions and experiences we remember from our early years can help to shape who we are as adults, determining our likes, dislikes, fears and even our behaviour.
  • Memories before the age of three are more than likely to be false. Any that appear very fluid and detailed, as if you were playing back a home video and experiencing a chronological account of a memory, could well also be made up. It is more likely that fuzzy fragments, or snapshots of moments are real, as long as they are not from too early in your life.
  • We crave a cohesive narrative of our own existence and will even invent stories to give us a more complete picture
  • Interestingly, scientists have also found positive suggestions, such as “you loved asparagus the first time you ate it” tend to be more effective than negative suggestions like “you got sick drinking vodka”
  • “Miscarriage of justice, incarceration, loss of reputation, job and status, and family breakdown occur,
  • One of the major problems with legal cases involving false memories, is that it is currently impossible to distinguish between true and fictional recollections
  • Efforts have been made to analyse minor false memories in a brain scanner (fMRI) and detect different neurological patterns, but there is nothing as yet to indicate that this technology can be used to detect whether recollections have become distorted.
  • the most extreme case of memory implantation involves a controversial technique called “regression therapy”, where patients confront childhood traumas, supposedly buried in their subconscious
  • “Memories are malleable and tend to change slightly each time we revisit them, in the same way that spoken stories do,”
  • “Therefore at each recollection, new elements can easily be integrated while existing elements can be altered or lost.”
  • This is not to say that all evidence that relies on memory should be discarded or regarded as unreliable – they often provide the most compelling testimony in criminal cases. But it has led to rules and guidelines about how witnesses and victims should be questioned to ensure their recollections of an event or perpetrator are not contaminated by investigators or prosecutors.
  • Any memories that appear very fluid and detailed, as if you were playing back a home video, could well also be made up
  • While this may seem like a bit of fun, many scientists believe the “false memory diet” could be used to tackle obesity and encourage people to reach for healthier options like asparagus, or even help cut people’s alcohol consumption.
  • Children are more susceptible to forming false memories than adults, especially after looking at photographs or films
  • And we may not want to rid ourselves of these memories. Our memories, whether fictional or not, can help to bring us closer together.
