Yes, tax refunds can be randomly selected for review, along with computerized screening and comparison of information (W-2s/1099s). The IRS uses random sampling to check for accuracy, and having a return flagged does not automatically imply fraud or error. While some selections are random, others are based on high Discriminant Function System (DIF) scores, which flag deviations from income/deduction norms.
