It’s relatively easy to market certain types of science writing. Many people are already interested in the life sciences. They are also certainly curious about it. All of the sciences require a relatively high level of training to understand. However, there are some people who are particularly interested in this subject, even if it is not an area of expertise for them.
People who have had a mild background related to the sciences can still know a lot about them, especially in an era where it is relatively easy for people to become self-educated on a wide variety of subjects. However, some people are not going to be interested in certain areas within the broader world of science. People are often more familiar with biology than they are with physics, at least in some cases.
Most people will need to know something about medicine just to get through the day, so learning about biology might be easier for them than learning about some of the other forms of science. Physics and engineering both require advanced mathematics skills, and some people have not learned those. People can read about biological subjects and learn a lot about them as it is, and this is going to increase demand for some of the life science content that will be available online in the modern world.
It will be easier and easier for people to find high-quality life science content these days. Most people will also find it relatively easy to understand it, since they can easily look up anything that they don’t understand. This was much harder in the past. It’s very difficult to learn math this way, but it might be easier for people to learn some other subjects this way. Life science marketing can be easier as a result.
