换句话说，弗林效应可能部分归因于这样一个事实，即在二十世纪，我们已经开始解决许多阻碍前几代人充分发挥其潜力的公共卫生问题。对弗林效应的另一种解释与过去一个世纪因工业革命而发生的社会变革有关。在TED演讲中，弗林解释说，今天的世界是“一个我们不得不养成新的心理习惯，新思维习惯的世界。”弗林发现，在要求我们找到的问题上，智商得分增长最快不同事物之间的相似性，以及解决问题的更抽象类型 – 这两者都是我们在现代世界中需要做更多的事情。已经提出了几个想法来解释为什么现代社会可能会导致智商测试得分更高。例如，今天，我们中的许多人都有苛刻的，智力严谨的工作。学校也发生了变化：虽然20世纪初的学校考试可能更侧重于记忆，但最近的考试可能更侧重于解释某些事情的原因。此外，今天更多的人可能完成高中学业并继续上大学。家庭人数往往较小，有人建议这可以让孩子在与父母互动的同时学习新的词汇。甚至有人认为我们消费的娱乐今天更加复杂。试图理解和预测喜欢的书或电视剧中的情节点可能实际上让我们变得更聪明。
In other words, the Flynn effect may be partly attributed to the fact that in the twentieth century we have begun to address many public health issues that have prevented previous generations from reaching their full potential. Another explanation for the Flynn effect is related to the social changes that have taken place in the past century due to the industrial revolution. In the TED talk, Flynn explained that today’s world is “a world in which we have to develop new psychological habits and new thinking habits.” Flynn found that IQ scores grew fastest on the questions we asked us to find. The similarities between different things and the more abstract types of problem solving – both of which are things we need to do in the modern world. Several ideas have been put forward to explain why modern society may lead to higher IQ scores. For example, today, many of us have demanding, intellectually rigorous work. The school has also changed: although the school exams of the early 20th century may be more focused on memory, recent exams may be more focused on explaining the reasons for certain things. In addition, more people today may complete high school and continue to go to college. The number of families is often small, and it has been suggested that this allows children to learn new vocabulary while interacting with their parents. Some even think that the entertainment we consume is more complicated today. Trying to understand and predict the love nodes in a favorite book or TV show may actually make us smarter.
