Research is hard work. Researchers may spend months, years, or even decades collecting data. Sometimes when researchers analyze that data and try to present it in a handful of published pages, it can be difficult to include every single thing they did, or to discuss all the problems they encountered in the experiment or study.
Luckily, we know that it is good to ask more questions, even of published research. Doing so gives you practice in critical thinking, a skill that is beneficial in any endeavor. After you read "Milk - It Does a Baby's Immune System Good" and maybe try your hand at the original article, "Illness in breastfeeding infants relates to concentration of lactoferrin and secretory Immunoglobulin A in mother's milk," think of some potential questions about the data, hypotheses, and conclusions that the researchers presented and see if you can come up with any holes in the study. Print out or copy down the questions below and think or write out your answers. When you’re done, visit our “Digging Deeper: Milk and Immunity” PDF to see what we came up with.
