I always tell my students that there is no such thing as multi-tasking. You can't do two things at the same time. You can alternate doing one thing at a time and get more than one thing done at the end of the period of time you spend alternating between tasks, but that is not multi-tasking. That is doing one thing at a time, and then doing something else, and then going back to what you were doing before. One thing at a time.
And now I can add to my "rant" that if you think you can do two things at the same time, you might be on your way to get disciplined.
In a case involving facts I have to admit I had never seen before, the Supreme Court of Kansas disciplined a lawyer for making a “materially false statement” in reporting his attendance at an MCLE program.
Here is how this relates to the issue of "multi-tasking": The false statement charge was based on the fact that the lawyer claimed more than eight hours of CLE in a single day. His explaination to MCLE authorites? He viewed an “online on-demand CLE program while sitting in live CLE program. Efficiency by multi-tasking at its best!
The lawyer actually argued that he was “overconfident” in his “abilities to multitask.” The Court, however, found that the lawyer engaged in conduct “involving dishonesty, fraud, deceit or misrepresentation.
The case is In re Mathews, No. 120,924 (Ks. Sep. 27, 2019).
