02:43 pm - Notes on the Acceleration: Days of Miracles and Wonder – Arms and Brains
Here's a short video piece on the latest (and exceedingly advanced in prosthetic limbs Limb regrowth is obviously superior to even the best prosthetics and tests of this are also underway.

Also, research into brain scanning is also doing well, here's a piece about the new fMRI lie detectors, I don't know the error rating on the new lie detectors, but if they can be made reliable enough, I'd like to see them use in trials and also to have politicians use them during at least some interviews. I rather like the idea of a society where people simply cannot effectively lie about anything that's considered sufficiently important to get out the lie detector.

Even more impressive is this article about being able to electronically decode thought. We're clearly heading towards some sort of direct neural interface, and I'm very eager to see the results.

That lie detector could easily be abused.

1. There is no such thing as hackproof technology. Someone could sabotage the machine and make it look like an innocent person was lying.

2. It would eliminate a suspect's right not to incriminate himself or herself. Everyone is guilty of something.

3. Would it be able to distinguish between someone who is telling the truth and someone who is mistaken/delusional? For instance, a delusioanl woman accuses her neighbor of sexually abusing his daughter. The lady in question would pass the lie detector test, which could result in the arrest of an innocent man.

That's definitely something that needs to be taken into account.

2. It would eliminate a suspect's right not to incriminate himself or herself. Everyone is guilty of something.

In a court at least, the issue would be (as now) what questions can be asked. You'd need strict guidelines, but if someone is only asked about the matter in question, then the issue of self-incrimination is IMHO irrelevant.

3. Would it be able to distinguish between someone who is telling the truth and someone who is mistaken/delusional?

I'm fairly certain that this tech can disginguish between most (perhaps all, I'm not certain) delusions and actual memories. However, all it can do is tell if someone is accessing an actual memory or not when answering a question, so an honest mistake would count as truth, which is really all you need for all manner of useful purposes like trials or questioning public figures.

Nothing in that article or that I've seen elsewhere distinguishes between delusion and memory. They distinguish between memory and confabulation, where the brain is doing extra work in the latter either to make something up, or to suppress the true memory, or both. A mistaken or false memory wouldn't have suppression issues, and if laid down previously by bad counseling or whatever, wouldn't obviously include "make this up right now" extra work. So it wouldn't clearly help in the delusional accusation case, or with all the uncertainty of eyewitness memories. Wouldn't pick up on half-truths, either.

Picking out deliberate lies would be pretty powerful, mind you, but it's not a judicial panacea.

I'm not certain that this is the same tech, but I've read about studies that said they could distinguish between created memories (along the lines of false recovered memories and suchlike) and actual memories using brain imaging. If this is the same tech, then it can definitely distinguish between false and real memories and could likely deal similarly with most delusions.

What isn't clear from this article is whether or not they can distinguish between lying and having to think hard to remember something that wasn't immediately accessible.

I don't remember the details, and I'm not certain that this is precisely the same tech, but I've seen a number of things about using fMRI to monitor activity in the hippocampus, and much of the way that truth is told from lies (and "recovered" false memories) is that no sensory data is accessed in non-true memories, so there is no activity in the sensory regions of the brain, while there is always such activity when recalling an actual memory. This seems like an ideal way to tell the difference between memories of actual events and everything but the most vivid delusions.

As kitten_goddess said, there's potential trouble with it. With any new technology like this, first consider, "what would the republicans do with it?" I tend to the more pessimistic on what society evolves into in that regard.

But yes, conversely, there are some people in Washington I'd love to grill under one of these things too.

Interesting times.

Unfortunately, if these things become easy enough to use, nothing will be considered "true" unless it's confirmed by the lie detector.
