Lie

1. as a saying goes, "honesty is always the best policy." while it is very true, for me, to keep our society moving, we really need certain amount of "lie"

2. just imagine how uncomfortable (or chaotic) our society would be if all the compliments we paid to our superiors, lovers, and etc were exposed as lies? won't it be bad?

3. but, too much lies would only cause destruction to our society. thus, scientists are working hard to improve current lie detectors.

4. according to Daniel Labgleben, whenever someone telling lies, his/her brain activity in several areas would  increase significantly - e.g. frontal lobe, temporal lobe, and limbic system.

5. this unusual increase of brain activity can be detected through brain scan (e.g MRI). this technology is claimed to be more efficient since altering brain pattern is beyond man's capability. in other words, "our brain pattern won't lie"

6. yet, many critics believed that MRI doesn't detect lie, but only the increased of brain activity, which can be due to many reasons.

7. in conclusion, MRI fails because of the following reason:
   7.1 as telling lies would increase our brain activity is true, but to say that the increased of brain activity is  
         solely because of someone telling lies is indeed not true.

8. but, i believe the ideal solution for this problem is to make the impossible "telepathy" possible.

9. brain, in principle, is a transmitter (receiver), in which thoughts are broadcast (received) in electrical signals.

10. so, to intercept one's thought can be easily done by capturing and interpreting the signal.

11. however, the problems with this signal are as follows:
     11.1 the signal is too weak
     11.2 the signal is too gibberish, and thus cannot be separated from background noise
     11.3 our brains cannot "interpret" or decode the information from the signal received

 12. but, these problems aren't insolvable. my simple thought would suggest the followings:
     12.1 we can amplify the signal to make it louder
     12.2 then, we can filter the signal. i bet the signal from our brain activities would be slightly different from  
             the background noise (e.g. frequency)
     12.3 then, the signal should be modulated before being broadcast. then, as we know the modulation type,
             the demodulation task would be much easier

13. and of course, it's easier said than done. and i'm pretty sure that my suggestions are premature..but, in science, no problem is insolvable..thus, i believe, it's just a matter of time before this telepathy is made possible..by that time, telling lies would be the hardest thing to do..
