1.Researchers base their discoveries on various sources when they present the spread of reading ability. The tendency is that each of us has a special trust in exactly that type of sources we make use of in ourselves in our own research, be it the spread of organized schools, signed wills, autobiographies, number of published books etc. The results we obtain seem to differ, sometimes to an astonishing degree.
研究者们在阐述阅读能力的范围时是基于他们在各种信息来源的发现之上的，趋向于我们每一个人恰好对我们在自己的研究中利用的资源类型本身特别信赖，它的范围是有组织的学校、已签署的遗嘱、自传、大量已出版的书籍等等。我们获得的结果似乎是不同的，有时甚至到了另人惊讶的程度。
