Discounted

"Like airlines, when demand is high for travel to sporting and cultural events, rail customers can expect to pay higher fares with restrictions placed on the sale of discounted saver and supersaver tickets."

"John A. Hobson, the radical British economist and publicist, in his book entitled Free Thought in the Social Sciences faces frankly the difficulties just indicated and urges a change of procedure on the part of the workers in the social sciences. Instead of ignoring bias, of tacitly assuming that it has been somehow exorcised by writers, M. Hobson advises recognition of inevitable bias and making proper allowance for it. […] In the end, the hypothesis is, the sum of such duly discounted assertions and affirmations will furnish material for a true science. Unfortunately, it is easier to propose this method than to apply it. What is a proper discount in any of the cases given for illustration? Will not bias enter into the determination of the discount?"
