Better and Better Day 66
Today we will learn the diffusion rate of new things. When journalism studied mass communication, it found a rule that any new thing became widely known from never known, whose diffusion rate was not uniform. It’s slow at first, and when the size of the population that accepts it reaches a critical point, the diffusion rate suddenly accelerates, and then slows down when it reaches a certain level. Because the crowd is usually normal distribution. After all, the risk taking is a minority, the middle mass group is the largest. New things only touch the middle part of the crowd, can really usher in the take-off point. According to the characteristics of normal distribution, this critical point of diffusion rate will be in the 10%-25% range.
今天我們來學習新事物的擴散速度。新聞學在講究大衆傳播時，就發現一個規律。任何一個新事物，從不爲人知，變成廣爲人知，它的擴散速度不是均匀的，一開始比較慢，當接受人群規模到了某個臨界點，擴散的速度會突然加快，等到了某個水平，又會慢下來。因爲人群通常是正態分佈，敢于第一個吃螃蟹的畢竟是少數，處在中間的大衆群體是最多的。新事物衹有觸達中間這部分人群，才算真正迎來起飛點。根據正態分佈的特點，這個擴散速度的臨界點一般在10%-25%這個範圍。
