  2. Find and read through a research paper once.
  3. Write down your takeaways.
  4. Find and read a research paper disagreeing with this concept.
  5. Write down your takeaway on a separate piece of paper.
  6. Compare the takeaways and understand the contrasts. In other words, assign the x-ray fish role and the person with no point of reference.
