摘要:We are largely ignorant. At least, there are many more things we are ignorant of than knowledgeable of. Yet, the common perception of ignorance as a negative trait has left it rather unloved in debates around making knowledge public, including science communication in its various guises. However, ignorance is a complex and essential part of science; it performs a number of legitimate roles, and is performed in a range of legitimate ways within science. In this paper, I argue that it is vital to understand when ignorance is an appropriate, legitimate part of the scientific process, and when ignorance is misused or abused in science. I argue that understanding ignorance is a central aspect of public understanding of science, especially in terms critical science literacy. Critical science literacy argues that more than simply an understanding of scientific facts and processes, a key component of what scientific literacy should aim for is an understanding of the tacit knowledge of science. I present a typology of ignorance and argue that fostering a greater public understanding of ignorance is a rarely acknowledged, yet essential, aspect of making science public, and that it is a challenge that those engaged in and committed to better public understanding of science should take very seriously.
