回复 #310 壮家汉 的帖子
这现象可以看以下内容便可以解释。其中一个人的盲听就只对他自己来说是真的,对别人来说没有参考意义。

how do you know the difference is real or you just imagined it? if it is real, somebody else who don't know what you have done should be able to tell it, right? if so, it will show up in a blind listening test. if it doesn't show up in a blind listening test, it is not real.
你怎么知道这听感是真实的?如果这是真的,别的人不知道你用什么方法能够得出这结果,对吗?假如这样的话,这将是双盲试验的结果,如果不是双盲试验的结果,这不是真的。

what science has established is that our brains are extremely powerful in imagining things that don't exist - that is called the placebo effect. that is why in drug testing, they use double blind tests to eliminate placebo effect, which unfortunately is the only known way to do that.
科学已经证实我们大脑有想像本来不存在的幻想的强大功能————那叫做安慰剂效果。那就是为什么药物试验,必须用双盲试验排除安慰剂效果的影响。那不幸的是唯一的做那试验的科学方法。

不是每个人的盲听结果都可以作为参考依据。
a particular's individual's blind listening results may not have any relevance to the general public. It sure has 100% relevance to that person. so while you can pass a blind listening tests doesn't mean that the difference is there for the general public, it sure says that a difference exists for you.
blind listening is valid for the public only if a large enough sample of people have passed that blind test. This is a much higher hurdle to clear than the individuals passing a blind test individually.
another way to say it is that it is a lot tougher for a given product to pass a blind listening test for multiple individuals in a statistically significant fashion.
一个特定的个人盲听结果和公认的盲听评测没有任何关系,它仅仅确实和那特定的个人有100%的关系,因此你个人通过的盲听试验不意味着有公认的意义,这只能够说对你自己存在意义。
只有通过足够多的人数的样本取得的盲听结果才被公认,大样本的盲听比个别人的盲听有更高的执行标准。
换句话说,就是,用更为科学有力的统计分析的方法处理盲听的结果。 |
