    Somehow I think 50 million years to human evolution has both bred people who can convince others to do what they want and people resistant to that appeal that in both cases will be no match for any analytical approach to dissecting human puchasing habits.

Homo species prior to Sapiens probably didn't have the kind of symbolic processing ability that would make such linguistic or visual appeals, or the the ability to resist them, evolutionarily important, even if they had language, which is also under question.

    Advertising has a large unconscious component; anyone who has lived in this modern world for any stretch of time knows that. This is just the first time (probably not even) that it's been documented with medical evidence.

    fMRI is a great research technique -- I've worked with it for years -- but I think that zealous companies that want to find the best way to tickle comsumers' brains are going to be pretty disappointed in fMRI as a marketing research tool. (And at $400+/hr, their disappointment is going to cost them . . .)

    What these companies want is to be able to look at a scan of someone viewing/thinking about their product and to then be able to say, "Aha, he really wants this!", or, "She is debating on whether shee needs this," or even perhaps, "This product makes him feel secure."

    That's bullshit -- its mindreading -- and given what we know about the brain and the signals that can be read in an fMRI, it can't be done. Perhaps one day, far in the future, something like that will be possible. Right now, though, people are still debating what exactly it means (in terms of neural activity) when you see a brain region "light up" in an fMRI scan. And even if we could know how exactly fMRI signals and neural activity relate, there's still a /vast/ dearth of knowledge about what various brain areas actually do, what they represent and how, etc. Maybe one day neuromarketing will pay off, but I honestly don't think it will be any time soon.

    So many studies are done about consumer behavior and advertisers' tactics and, yet, consumers behave exactly as they did before. For example, research [washington.edu] by Elizabeth Loftus [uci.edu] at UCI has shown that advertisers like Disney routinely implant memories into us. In one of her studies, subjects even believes that they had seen Bugs Bunny at Disneyland. Even after this was widely reported by the media, Disney ads have stayed the same and are still as likely to "fall prey" to them.

    Obviously, the benefits to advertisers and consumers are quite asymmetrical from all this research. Advertisers can actually refine their techniques and perhaps learn new ones. Consumers, on the other hand, may be a little more educated but they certainly are more easily seduced. While this is not absolutely bad and may even be good in some ways, the fact remains that with increasingly power research tools like fMRI mentioned here, the potential for corporations to absolutely manipulate us increases. I'm sure that things will work out in the future, as they have always done. However, research into "defenses" against memory implantation, et al does need to be conducted.

    What's more, the brain activity of the subjects was now different. There was also activity in the medial prefrontal cortex, an area of the brain that scientists say governs high-level cognitive powers. Apparently, the subjects were meditating in a more sophisticated way on the taste of Coke, allowing memories and other impressions of the drink -- in a word, its brand -- to shape their preference.

    Note the bias here in the interpretation of the results. The eliciting of a stronger response in more primitive areas of the brain - which Pepsi reportedly does when neither is named - is viewed as the more objective reality. While a response which involves higher areas of the brain which are concerned with the aesthetics of it is just a matter of "brand." Further, there's the implication that when the higher areas of aesthetic appreciation are active we're being more manipulated by brand, and missing the reality, as defined by the most primitive reaction, which could well be based on Pepsi having a sweeter taste.

    In all likelihood a splotch of bright red will have a stronger reaction from primitive brain areas than will a fine landscape painting (we're strongly programmed to respond to red since it's often a sign of blood and danger). By the logic of this researcher (at least as reported by the Times) our considered preference for the landscape painting over the splotch of bright red is a sort of manipulation by the brand "landscape painting," or perhaps the brandname of the painter. While there's some small degree of truth to this, isn't it largely back asswards?

    Firstly, you can't have a "stronger" or "higher" or "larger" fMRI response - the most you can have is a larger probability that the signal you are reading in a particular region of the brain is not due to chance but to manipulation of your experimental variable (in this case, the drink being drunk).

One of my supervisors was approached a couple of years ago by a film distributor, who wanted to show fMRI pictures of someone just sitting, versus someone reading a book, versus someone watching a film - the desired effect being, of course, to show that films recruit more of the brain. Duh! It would have worked, and been a legitimate thing to do - but they wanted it in a matter of days (and with pretty pictures too!) - this stuff takes time, at least with our facilities it does. So, no deal. In terms of whether fMRI and similar techniques tell you anything ... hmm. Kinda. But results are consistently over-interpreted by many in the scientific community, and as has been pointed out in other posts, fMRI measures local blood flow, not neuronal activity (blood flow, by the way, can be influenced by a variety of factors, such as caffeine, which is a vasodilator ... so if either Coke or Pepsi contained more caffeine than the other, that could partially account, potentially, for differential fMRI results) And don't even start me on using functional imaging techniques as "lie-detectors" ... There's a long way to go, and anyone who says different really IS selling something.
    • A few points here are worth clarifying. First, certainly you can have a stronger fMRI (i.e., BOLD) response in one stimulus condition vs. another. What you can't know for certain, generally, is whether a given difference in mean signal is really due to a stronger BOLD response (vs. noise). But that's what statistics are for. So a comparison of this kind is not necessarily meaningless.

      Second, anyone who's both done science and read science reporting knows that the quality of science reporting in the pop

  • Personally, all the money spent on advertising is wasted on me. Simply because of the obnoxious ads, either content or running the same lump'o'doodoo 2 or 3 times in a row, I will not buy that product. Whenever an ad comes up, I either change the channel or radio station. Take that Ad Exec and smoke it.

  • I wasn't very happy with the article. I can taste the difference between Coke and Pepsi, and I like Coke better, as do most people. Pepsi has a more sugary taste. People apparently don't want that in a strictly recreational drink. Beer is another example; it is bitter.
  • Thus far, I've seen a lot of posts saying that this doesn't work or that if it works then it's a terrible thing because it gives advertisers the ability to manipulate the subconscious mind to make you buy stuff you don't need. But, there's a greater question of ethics here. Why are these advertisers being given access to a scarce medical research resource (magnet time) when there are so many other things that could be done with that resource for the benefit of humankind? How can someone's priorities be s
    • In my experience, what happens is that a scanner is bought for a hospital and/or research dept, costing around 3million (c. $5 million). To claw this money back, the number of hours of function that the scanner will likely achieve in its lifetime is estimated, and this is how much you charge per hour for its use.

      Certainly where I was doing my research, the scanner sat empty and unused for at least one quarter of the time. It seems that it's harder to get money to do the research you want (I was looking at
  • ...welcome the new fMRI overlords!

    Actually, it will be both funny and sad when/if this stuff is actually used. Funny since it won't work on me, marketing shit never has. Sometimes it's really funny how hard they try. Sad in seeing the number of dogs-drooling-at-Pavlov's-bell types wondering around, unaware of their plight...
  • Despite the fact that subliminal advertising has been proven not to work, some major corporations continue to pay big bucks to have it added to their ads. Despite the fact that 90%+ of fMRI research claims to find the place in the brain that lights up when X happens (rather than more properly claiming they're seeing the location of the brain process that supports such phenomena as X) the suits are going to continue to believe that neuroscientists can narrow down the brain parts that make you prefer one cola
  • Here for $0 I'll tell you what consumers want:

    1) free stuff
