Is the divide between hard and soft science a fact or a feeling?

In short: We often treat the distinction between hard and soft sciences as an objective truth. But is it a measurable reality or a social construct? While some data suggests a hierarchy exists, the line between 'rigorous' and 'subjective' is often blurred by history, gender bias, and the way we value human experience.

The terms 'hard' and 'soft' science are colloquial labels used to rank disciplines based on perceived methodological rigor, objectivity, and exactitude. Historically, the idea of a scientific hierarchy dates back to the 19th-century philosopher Auguste Comte, who ranked sciences based on their intellectual development and complexity. In modern contexts, hard sciences typically refer to formal and natural sciences, while soft sciences encompass social sciences. These labels often imply that hard sciences possess superior qualities like faster progression, greater explanatory success, and a 'purer' form of the scientific method.

However, the evidence for these distinctions is nuanced and often contested. Critics point out that many 'soft' sciences, such as psychology and sociology, utilize complex mathematical models extensively. Conversely, some 'hard' sciences, like astronomy and geology, are unable to perform controlled experiments and must rely on observation and natural experiments. Furthermore, the 'replication crisis' has shown that the failure to reproduce findings is a systemic issue affecting both the natural sciences and the social sciences alike. Some researchers argue that the distinction is less about methodology and more about a stigma that impacts funding and public recognition.

Despite these critiques, some empirical data suggests a measurable hierarchy. A 2000 study by Smith found a near-perfect correlation between the frequency of graph usage in journals and a field's perceived hardness. Additionally, research by Fanelli in 2010 and 2013 suggests that 'softer' sciences may have fewer constraints on researcher bias, leading to higher odds of positive results, while 'harder' sciences show a greater ability to achieve scholarly consensus. Ultimately, the debate highlights a tension between the desire for objective classification and the reality of how society values different types of knowledge.
