Softening Up Hard Science: Reply to Newell and Card

A source of intellectual overhead periodically encountered by scientists is the call to be hard, to insure good science by imposing severe methodological strictures. Newell and Card (1985) have undertaken to impose such strictures on the psychology of humancomputer interaction. Although their discussion contributes to theoretical debate in humancomputer interaction by setting a reference point, their specific argument fails. Their program is unmotivated, is severely limited, and suffers from these limitations in principle. A top priority for the psychology of human-computer interaction should be the articulation of an alternative explanatory program, one that takes as its starting point the need to understand the real problems involved in providing better computer tools for people to use. 1. Newell and Card on Being Hard Newell and Card (1985) have presented a program for psychological research in humancomputer interaction couched as an analysis of how psychology can avoid being ...
