I’d barely started to grasp the concept of click-jacking. (And surf-jacking , modem-jacking, car-jacking, rate-jacking etc.)

Now, we also have to worry about “brain-jacking”, according to the Times.

It sounds like science fiction, but politicians, lawyers and advertisers are falling over themselves to buy into the latest scientific discovery: brainjacking. Soon our secret desires and not so innocent thoughts could become public knowledge. John Naish investigates an uncomfortable trend (sub-heading to the Times article)

The idea that machines can determine our true thoughts and feelings isn’t just silly (although, on present showing, it certainly seem to be that) but dangerous. It has already been used in several Indian cases that involved serious crimes, despite the opposition of scientists:

Although an Indian government panel of scientists says this technique, Brain Electrical Oscillation Signature profiling (BEOS), should be ignored, its use in India is spreading

I was pretty scathing about lie-detection technology a few weeks ago.

This sparked the researcher Aiden Gregg to put up an elegant defence of his work in the comments here. I was feeling a bit guilty for randomly splattering out knee-jerk scepticism, when his careful research itself couldn’t be held to blame for how it might be misused by people who don’t understand probabilities. But he said this:

However, as an asserted lie detector, the VSA may intimidate benefit claimants into bring more truthful in general. Ironically, this would involve telling a lie to deter lying.

I don’t think that ironically is the right word, here. I think that unethically is more appropriate. (And that’s ignoring the tendency of the innocent to feel guilty in the face of any interrogation and intimidated in the face of prying authority. Although, maybe, deterring as many claimants as possible is the true objective.)

The Indian courts might be able to intimidate the gullible-guilty into thinking that their brains have given them away. This will not work on the less-gullible guilty. The process could even work to give them an unearned apparent veracity.

The process is basically a conjurer’s mind-reading trick, with science-y looking props. If I had access to a million-dollars, so that I could offer a Randi-style million dollar challenge, I’d happily bet myself against a mind-reading machine as being just as likely to tell who was lying. I think I’m quite good at it. I wouldn’t claim more than 85% success rate but nor do the machine-minders.

So, not having a million dollars, I am setting up the “Ned Ludd Memorial Mind-reading Machine-breaking Challenge.” I will give £20 to the first person who can best my truth-detection skills with some new-fangled electrodes-in-skull contraption.
