 This view and the case study have recently been challenged by Schindler (2011). He argues that the tested theory was critical in the assessment of the reliability of data in the experiments with weak neutral currents. He also points out that, on occasion, experimental data can even be ignored if they are deemed irrelevant from a theoretical perspective that physicists find particularly compelling. This was the case in experiments with so-called zebra pattern magnetic anomalies on the ocean floor. The readings of new apparatuses used to scan the ocean floor produced intriguing signals. Yet the researchers could not interpret these signals meaningfully or satisfyingly distinguish them from noise unless they relied on some theoretical account of both the structure of the ocean floor and the earth’s magnetic field.
