Scientists are often known for their use of technical jargon to communicate complex ideas with precision. This jargon is essential for avoiding confusion and ensuring that scientific concepts are clearly understood. However, in addition to specialized terminology, scientists also assign specific meanings to everyday words and phrases, which can take on additional nuance in a scientific context.

One example is the word “risk,” which can mean different things depending on the field of study. Engineers might use it to refer to the likelihood of a bridge collapsing, while economists might use it in the context of financial loss. Environmental scientists, on the other hand, might use it to signal potential harm to a species or habitat. Without specifying the context, statements about risk can justify a wide range of decisions, from infrastructure improvements to ignoring environmental concerns.

Unfortunately, malicious actors often exploit this ambiguity to advance their own agendas, spreading disinformation and sowing confusion. This can have harmful effects on communities, health, and the environment. During the Trump administration, there was a coordinated assault on science and scientific integrity, leading to policies that distorted scientific evidence for political gain.

To counter these attacks on science, it is important to understand and defend key concepts such as “best available science,” “scientific consensus,” and the role of uncertainty in scientific research. Best available science refers to the most reliable and up-to-date empirical knowledge, which is used in decision-making processes by government agencies. Scientific consensus represents broad agreement among scientists based on multiple lines of evidence and peer-reviewed research. Uncertainty is a crucial aspect of scientific inquiry, and scientists work to quantify and communicate it in their findings.

Protecting scientific integrity is essential for ensuring that rigorous research guides decision-making processes. When key scientific principles are compromised, the consequences can be far-reaching, impacting public health, environmental sustainability, and democratic institutions. Defending science requires collective action from policymakers, educators, advocates, and the public to ensure that scientific evidence continues to inform policy decisions in a transparent and robust manner.

As we face the challenges of the second Trump administration, it is more important than ever to uphold the values of science and work towards a future guided by evidence-based decision-making. By defending science and scientific integrity, we can ensure a healthy, safe, and just world for all.
