Aircraft
Upon rotation on takeoff; I noticed the stall barber pole was higher than normal and the low speed awareness cue was equal to to it. There were no messages and no faults displayed on the MDC. We took off at the appropriate flap setting and the FO's (First Officer's) display appeared normal. We elected to request expedited handling and to return to field to mitigate delays and to make sure that a larger problem did not exist. To prevent the stall protection system from falsely activating we turned off the captain side stall protection switch; ran the STALL FAIL caution message QRH; applied the safety reference and landing distance additives; and landed on runway XXC in ZZZ. We parked at gate XX; deplaned; and were reassigned a new tail.
Captain reported unreliable airspeed and stall protection system indications and elected to request expedited handling and an air turn back to a successful precautionary landing.
