Branch is a prominent critic of creationism and intelligent design having published multiple papers on both. He emphasizes the need of appreciating creationists' actions at the different levels of educational governance, and the need to change tactics in fighting against them. He believes scientists are in a unique position to defend the teaching of evolution, both by resisting creationist incursions as they occur and by helping to improve the teaching of evolution at both the precollege and college levels. Branch criticized how creationists call evolution a theory in an NPR interview. "In everyday conversation, a theory is a hunch or guess,... That's not how scientists use it. For scientists, a theory is a systematic explanation for a range of natural phenomena." Branch was involved in the campaign against the Discovery Institutes’ “Teach the Controversy,” a challenge to the key principles of Darwinian evolution based on an annotated bibliography of 44 peer-reviewed scientific article which were said to raise doubts about Darwin’s theories. The bibliography title “Bibliography of Supplementary Resources for Ohio Science Education" was analyzed by the staff of the National Center for Science Education with the assistance of many of the authors of the publications listed in it, finding that the Discovery Institute misrepresented the significance of the publications in the Bibliography, described the publications in the Bibliography in a frequently inaccurate and tendentious manner, and fails to present any principled basis for the publications selected nor any pedagogical rationale for the use of the publications in the classroom. NCSE concluded that the only purpose of the Discovery Institute's Bibliography was to mislead members of the Board of Education and of the public about the status of evolution. In an opinion piece written with Eugenie Scott, the coauthors stated that it “is scientifically inappropriate and pedagogically irresponsible to teach that scientists seriously debate the validity of evolution.” Branch was also highly involved in the effort to combat New Mexico's proposed change in Science standards in 2017. NCSE coordinated the effort to educate the public through journalists and activists and was able to successfully affect the regulators. As a result of the campaign, the New Mexico's Public Education Department announced that instead of the flawed standards originally proposed, it would be adopting the Next Generation Science Standards. Branch is a vocal critic against the movement of climate denial. He believes one of the most effective ways to improve awareness of climate change is through school education by science teachers. He states that this is a difficult task due to multiple issues of limited federal role, state attacks on science, local attitudes, etc. An increase of bills aimed at changing standards for climate science education introduced by state officials in early 2019 has signaled concern. "The only way to be sure they don't pass is to raise public awareness of them and to localize concerns about the integrity of public science education by speaking about them." At the 2019 SkeptiCal conference held in San Francisco, Branch presented a history of the Flat Earth movement which began in 1819 and evolved into the movement of today. He attributes the resurgence of the movement to a YouTube video posted in 2011 entitled “The Globe Model Attempts to Deceive the Public.” According to Branch, the old flat earth theory focused on creationism is dying out, while the new version is fueled by social media feeding conspiracy theories to people and pushing them further down the rabbit hole. Ultimately, Branch thinks the craze is going to fail for a lack of consensus between methods. Susan Gerbic agrees with Branch, stating “…they also don’t have scientists, strong leaders, and an organization.” In closing his talk, Branch said “National Center for Science Education will be there to fight,” no matter what happens.
