Narrative:

We received a preliminary dangerous good print out after we initialized ACARS. Then about 10-15 minutes to punch we received another preliminary dangerous goods printout that added more dry ice. I looked at this saw the addition of the ice and my expectation bias led me to believe that it was the final dangerous goods printout. We taxied and waited for our weight and balance numbers. When our final weights came the final dangerous goods also printed out and I said; 'why did we get another final dangerous goods report.' I then looked at the two reports I had and realized they were both preliminary reports.
