Data in other fields is unreliable as well, just less so, and we are constantly coming up with new technologies to improve our capabilities for data collection

Data in other fields is unreliable as well, just less so, and we are constantly coming up with new technologies to improve our capabilities for data collection in the hard sciences. Data collection is just one aspect of science. Should we eliminate the field of theoretical physics because they can't collect data and run experiments to test their theories?
