Had they done this and followed up CORRECTLY with the blindingly obviously necessary UNRELIABLE AIRSPEED checklist this whole disaster would almost certainly not have happened.
Here's a tip: get off your high horse and into the FCOM. Especially the system description of the stall warning. You’ll find this information which you would know anyway if you ever performed a 737 preflight:
“The SMYD Computers provide outputs for all stall warning to include stick shaker and signals to the pitch limit indicator and airspeed displays and the GPWS windshear detection and alert.
Two test switches are installed in the aft overhead panel. Pushing either of these initiates a self-test of the respective stall warning channel. The No1 activates the Captain stick shaker and the No.2 activates the F/O stick shaker.
Either stick shaker vibrates both columns though column interconnects. “
