A Good Life and _____________.
You fill in the blank with your interest area. There are important items that Haidt didn't have time for, or didn't know enough about, that are near and dear to our hearts. Possible topics are pets, family, death, illness, free will, habits, humor, philanthropy, sports, travel, education, politics, activism.... The list is endless. First, decide on one topic for yourself.
Second, build an annotated bibliography showing your research on your topic.
I find that Academic Search Complete works well as a database. Locate two good articles on your chosen topic. Limit your search to full text and scholarly or peer reviewed items. No eBooks, no book reviews, no news articles, no encyclopedia entries. Scholarly articles from journals only! You will have to fiddle with search terms and do a lot of skimming of articles before you find one that works for you. Cite the article using MLA form (include database). Then annotate each article in 150 words (each!), using first person, showing how this piece is helpful to you when thinking of a good life.
