While what is said can be difficult to understand, what is not said may pose an even bigger challenge. Language is efficient, so often what goes without saying is simply not being said. It is left for the reader or listener to interpret underspecified language and resolve ambiguities, a task that we do seamlessly using our personal experience, knowledge about the world, and commonsense reasoning abilities. In many cases, commonsense knowledge helps EFL learners compensate for low language proficiency. However, what is considered “commonsense” is not always universal. Some commonsense knowledge, especially pertaining to social norms, differs between cultures. Can language technologies help bridge this cultural gap? It depends. Chatbots like ChatGPT seem to have broad knowledge about every possible topic in the world. However, ChatGPT learned about the world from reading all the English text on the web, which is primarily coming from the US, and thus it has a North American lens. In addition, despite being “book smart,” it still lacks basic commonsense reasoning abilities that are employed by us to understand social interactions and navigate the world around us.
