So, at the end of the day we are all in a dreamy state where any type of upgrade is the placebo effect,, a new 24" wide screen lcd monitor isnt really any better than a 15" crt.Logically it is not possible to make that assertion. Bias is unavoidable in any individual assessment where the individual KNOWS what has changed from situation A to situation B. This effect cannot be dismissed, it is always present. You can no more avoid the placebo effect than you can avoid gravity. Bias can be balanced and the overall effect compensated by using a double-blind but (as a scientist and having scrutinised large numbers of trials and junk science) if you stand your ground based on the placebo effect, your judgement is in error and your feet are on quicksand. Placebo is just another name for operator bias. Bias occurs whenever anyone involved in making the judgement have any knowledge of what has changed between the various times at which a judgement is made. Bias is unavoidable; you can only compensate for it, never avoid it.
heheh, would agree if it was a situation where he wanted the stylus,, but he didn't, so im afraid you are the one speaking rubbish (scientist or not).your reasoning is a little bit like my oldest lads, he has a degree in chemistry.in my system then (vinyl) i had a stylus that cost me £15.00 (a lot > then) vms15e mk11, and was going to upgrade so went round a mates > house and offered it to him, he was dubious, so said i would fit it > and if he didn't find any difference i would have it back,,i also > said i prolly wouldn't notice but he would, well, again he was blown > away and i was also,,,,, no placebo there either.Rubbish - you both knew the nature of the changes, the placebo effect had a significant effect upon both judgements.
blimey, im glad you don't work for me with such shuttered vision when a given upgrade is so blindingly obvious.when you have > listened to a system for years then make an upgrade change there are > bound to be differences you will notice good or badScience has proved again and again that if the judgement is made with knowledge of when the change was made, the judgement will reinforce the beliefs of those making the judgement with a statistically significant effect. Double-blind randomised trials are the only rigorous method of compensating for the ever present placebo effect, no amount of bluff and blustering will change the reality.
I saw them in 1974? DSOM and it was the most amazing sound ever (qtips were close) and heard it on the radio a couple of weeks later - dire! Its amazing what wanting to hear something as good can do for the experience! Tom te tom te tomgod ! your all nuts,, how can you compare a live show to something you hear on the radio ! (prolly not even vhf in those days)
You can put headphones on upside down? -(O_o)-
well, that band is meant to go under the chin isnt it ?
There has been a number of serious scientific papers questioning the size, relevance, and even existence of the placebo effect. One meta-analysis of placebo controlled trials which also included an untreated groups, showed no statistically significant improvement for non-subjective outcomes (i.e. People on placebos claimed they felt better, but when symptoms were objectively compared with the untreated group there was no observable difference). So whilst I'm fairly confident in the placebo effect being real, it isn't necessarily what explains many of the results of medical treatments effective or otherwise. It is also sloppy terminology to use it as a catch-all for the other effects.
thank you Simon,,
I would have loved to have seen Pink Floyd live, unfortunately by the time I was introduced to them they had just finished their Pulse concert so I was a bit too late. Still I have spent the years since getting to know some of their other stuff and I do like to put some of their stuff on occasionally when the wife and kids are out :-)Rob
the pulse dvd is pretty good even though a bit dated.
i am too, only trouble is that i seem to keep getting bad cans of lager that give me a head ache, usually the last can funnily enough.No doubt sugar pills would work on me, since they're like alcohol. > Strangely real alcohol doesn't do anything to me.You're immune to alcohol?
