We depend on others. We depend on others when we are sick or when we need help moving into a new house. We also depend on others for knowledge. We learn from books written by other people. Children learn from teachers in school. If we are lost in a city, we depend on others to help point us in the right direction.<\/p>\n

Focusing on the last example, if you are lost without access to a (digital) map, finding someone who can help is a good idea. First, you might look around and find someone who doesn\u2019t herself look lost. You might also look for someone who seems available for questioning. The ideal person is someone who is likely to be reliable and receptive to your plight. Depending on how urgent it is for you to quickly make it to your desired destination, you might even ask more than one person. If you do decide to ask a second person, you wouldn\u2019t ask the traveling companion of the first person you asked. You\u2019d want to find someone else, someone who is independent from the first. You do this because you don\u2019t want to depend solely on the knowledge or goodwill of one person when it counts.<\/p>\n

Consider another example. Imagine you are diagnosed with a serious medical condition. It is not the kind of condition that is life threatening, but one that requires major lifestyle changes and daily medication. Since the diagnosis is life altering you seek a second opinion. However, not just any second opinion will do. The second opinion should be in some way independent from the first. This might require going to another medical practice down the road. You do this because you don\u2019t want to depend solely on the knowledge or goodwill of one person, or one clinic, when it counts. After all, the whole point of a second opinion is to get a fresh perspective on the medical evidence at hand. Doctors in the same clinic talk, which can muddle the fresh perspective you are seeking.<\/p>\n

Network epistemology takes as its starting point that we are all embedded in an inter-connected epistemic community of dependence.[1]<\/a> It says that in order to evaluate our epistemic lives, we need to see the structure of this dependence and the degree to which our epistemic lives depend on the goodwill\u2014or true beliefs\u2014of a few. The broader and more independent our sources are within our epistemic communities, the less dependent we are on the goodwill of others and the greater opportunity we have for sustained epistemic growth and intellectual autonomy.<\/p>\n

For example, in a star network (Fig. 1) information is filtered through a single central source. The center node (the source node) is the only source the outer nodes rely on for information. Each outer node is dependent on the single center node. Epistemic networks that are structured like star networks are associated with a number of problematic and harmful practices. Sexual predators and their targets often form a star network, with the predator at the center and the victims on the points of the star. This keeps the victims from effectively communicating with one another, and coordinating or cooperating against the predator.[2]<\/a> Star networks are also associated with financial fraud,[3]<\/a> academic fraud,[4]<\/a> and terrorist activities.[5]<\/a> This isn\u2019t surprising when we notice that a star network forms a structure of dependence that can easily lead to epistemic manipulation. If someone has only one source of information on a particular subject, and that source works to limit communication between others that utilize that source, there is no space for intersubjective validation. The more dependent we are on a few people, the more insecure our epistemic network is, and the more vulnerable we are to manipulation.<\/p>\n

\"\"<\/p>\n

Fig. 1 Star Network<\/p>\n

Network-security is worth aiming for even if it does not increase the likelihood of true beliefs. To see why, consider a non-epistemic case drawn from the history of philosophy. Kant put forward an argument that political rights are necessary for personal freedom and autonomy. Without these rights, the well-being of people is dependent on the goodwill of the strong or the state. In the case where the strong or the leader of a society has goodwill, political rights don\u2019t make a practical difference to those living in the society. However, their well-being is still less secure<\/em>. If the leader is replaced, or the strong have a change of heart (for the worse), then the weak have no protections. So even if political security does not make a practical difference in the day-to-day lives of people, having those rights secures personal freedom and autonomy currently, and in the case of change. Otherwise, it is just a matter of luck, or happenstance, that each person\u2019s well-being is respected.<\/p>\n

We find analogous results in the epistemic case. If you are in an insecure epistemic network, like a star network, but the source you rely on is reliable, trustworthy and accurate, then it might seem as though nothing is epistemically out of place. After all, you have access to true and reliable information. However, there is a strong sense in which your level of epistemic autonomy is diminished, with little opportunity to grow epistemically. In a star network, there is no exchange of differing ideas, and such exchanges can spur independent, critical, and creative thought. Moreover, just as in the political case, if the source has a change of heart, whatever good epistemic position you had is lost, without any clear opportunity to redeem it. You might not even notice something has changed.<\/p>\n
