My Parents Raised Me to Be a Science Denier, So I Educated Myself
A religious family attends church.
The Internet has made it easier than ever to misguide people. The anti-vaxx movement, climate change denial, protests against stem cell research, and other movements like these are rooted in the spread of misinformation and a distrust of science.
"I had been taught intelligent design and young-earth creationism instead of evolution, geology, and biology."
Science illiteracy is pervasive in the communities responsible for these movements. For the mainstream, the challenge lies not in sharing the facts, but in combating the spread of misinformation and facilitating an open dialogue between experts and nonexperts.
I grew up in a household that was deeply skeptical of science and medicine. My parents are evangelical Christians who believe the word of the Bible is law. To protect my four siblings and me from secular influence, they homeschooled some of us and put the others in private Christian schools. When my oldest brother left for a Christian college and the tuition began to add up, I was placed in a public charter school to offset the costs.
There, I became acutely aware of my ignorant upbringing. I had been taught intelligent design and young-earth creationism instead of evolution, geology, and biology. My mother skipped over world religions, and much of my history curriculum was more biblical-based than factual. She warned me that stem cell research, vaccines, genetic modification of crops, and other areas of research in biological science were examples of humans trying to be like God. At the time, biologist Richard Dawkins' The God Delusion was a bestseller and science seemed like an excuse to not believe in God, so she and my father discouraged me from studying it.
The gaps in my knowledge left me feeling frustrated and embarrassed. The solution was to learn about the things that had been censored from my education, but several obstacles stood in the way.
"When I first learned about fundamentalism, my parents' behavior finally made sense."
I lacked a good foundation in basic mathematics after being taught by my mother, who never graduated college. My father, who holds a graduate degree in computer science, repeatedly told me that I inherited my mother's "bad math genes" and was therefore ill-equipped for science. While my brothers excelled at math under his supervision and were even encouraged toward careers in engineering and psychology, I was expected to do well in other subjects, such as literature. When I tried to change this by enrolling in honors math and science classes, they scolded me -- so reluctantly, I dropped math. By the time I graduated high school, I was convinced that math and science were beyond me.
When I look back at my high school transcripts, that sense of failure was unfounded: my grades were mostly A's and B's, and I excelled in honors biology. Even my elementary standardized test scores don't reflect a student disinclined toward STEM, because I consistently scored in the top percentile for sciences. Teachers often encouraged me to consider studying science in college. Why then, I wondered, did my parents reject that idea? Why did they work so hard to sway me from that path? It wasn't until I moved away from my parents' home and started working to put myself through community college that I discovered my passion for both biology and science writing.
As a young adult venturing into the field of science communication, I've become fascinated with understanding communities that foster antagonistic views toward science. When I first learned about fundamentalism, my parents' behavior finally made sense. It is the foundation of the Religious Right, a right-wing Christian group which heavily influences the Republican party in the United States. The Religious Right crusades against secular education, stem cell research, abortion, evolution, and other controversial issues in science and medicine on the basis that they contradict Christian beliefs. They are quietly overturning the separation of church and state in order to enforce their religion as policy -- at the expense of science and progress.
Growing up in this community, I learned that strong feelings about these issues arise from both a lack of science literacy and a distrust of experts. Those who are against genetic modification of crops don't understand that GMO research aims to produce more, and longer-lasting, food for a growing planet. The anti-vaxx movement is still relying on a deeply flawed study that was ultimately retracted. Those who are against stem cell research don't understand how it works or the important benefits it provides the field of medicine, such as discovering new treatment methods.
In fact, at one point the famous Christian radio show Focus on the Family spread anti-vaxx mentality when they discussed vaccines that, long ago, were derived from aborted fetal cells. Although Focus on the Family now endorses vaccines, at the time it was enough to convince my own mother, who listened to the show every morning, not to vaccinate us unless the law required it.
"In everyday interactions with skeptics, science communicators need to shift their focus from convincing to discussing."
We can help clear up misunderstandings by sharing the facts, but the real challenge lies in willful ignorance. It was hard for me to accept, but I've come to understand that I'm not going to change anyone's mind. It's up to an individual to evaluate the facts, consider the arguments for and against, and make his or her own decision.
As my parents grew older and my siblings and I introduced them to basic concepts in science, they came around to trusting the experts a little more. They now see real doctors instead of homeopathic practitioners. They acknowledge our world's changing climate instead of denying it. And they even applaud two of their children for pursuing careers in science. Although they have held on to their fundamentalism and we still disagree on many issues, these basic changes give me hope that people in deeply skeptical communities are not entirely out of reach.
In everyday interactions with skeptics, science communicators need to shift their focus from convincing to discussing. This means creating an open dialogue with the intention of being understanding and helpful, not persuasive. This approach can be beneficial in both personal and online interactions. There are people within these movements who have doubts, and their doubts will grow as we continue to feed them through discussion.
People will only change their minds when it is the right time for them to do so. We need to be there ready to hold their hand and lead them toward truth when they reach out. Until then, all we can do is keep the channels of communication open, keep sharing the facts, and fight the spread of misinformation. Science is the pursuit of truth, and as scientists and science communicators, sometimes we need to let the truth speak for itself. We're just there to hold the megaphone.
Sexually Transmitted Infections are on the rise. This drug could stop them.
Cases of gonorrhea, chlamydia and syphilis soared last year, but researchers are finding that a drug known as doxy seems to reduce the number of infections.
Sexually transmitted infections (STIs) are surging across the U.S. to 2.5 million cases in 2021 according to preliminary data from the CDC. A new prevention and treatment strategy now in clinical trials may provide a way to get a handle on them.
It's easy to overlook the soaring rates of gonorrhea, chlamydia, and syphilis because most of those infections have few or no symptoms and can be identified only through testing. But left untreated, they can lead to serious damage to nerves and tissue, resulting in infertility, blindness, and dementia. Infants developing in utero are particularly vulnerable.
Covid-19 played havoc with regular medical treatment and preventive care for many health problems, including STIs. After formal lockdowns ended, many people gradually became more socially engaged, with increases in sexual activity, and may have prioritized these activities over getting back in touch with their doctors.
A second blow to controlling STIs is that family planning clinics are closing left and right because of the Dobbs decision and legislation in many states that curtailed access to an abortion. Discussion has focused on abortion, but those same clinics also play a vital role in the diagnosis and treatment of STIs.
Routine public health is the neglected stepchild of medicine. It is called upon in times of crisis but as that crisis resolves, funding dries up. Labs have atrophied and personnel have been redirected to Covid, “so access to routine screening for STIs has been decimated,” says Jennifer Mahn, director of sexual and clinical health with the National Coalition of STD Directors.
A preview of what we likely are facing comes from Iowa. In 2017, the state legislature restricted funding to family health clinics in four counties, which closed their doors. A year later the statewide rate of gonorrhea skyrocketed from 83 to 153.7 cases per 100,000 people. “Iowa counties with clinic closures had a significantly larger increase,” according to a study published in JAMA. That scenario likely is playing out in countless other regions where access to sexual health care is shrinking; it will be many months before we have the data to know for sure.
A decades-old antibiotic finds a new purpose
Using drugs to protect against HIV, either as post exposure prophylaxis (PEP) or pre-exposure prophylaxis (PrEP), has proven to be quite successful. Researchers wondered if the same approach might be applied to other STIs. They focused on doxycycline, or doxy for short. One of the most commonly prescribed antibiotics in the U.S., it’s a member of the tetracycline family that has been on the market since 1967. It is so safe that it’s used to treat acne.
Two small studies using doxy suggested that it could work to prevent STIs. A handful of clinical trials by different researchers and funding sources set out to generate the additional evidence needed to prove their hypothesis and change the standard of care.
Senior researcher Victor Omollo, with the Kenya Medical Research Institute, noted, “These are prevention interventions that women can control on their own without having to seek or get consent from another person,” as is the case with condom use.
The first with results is the DoxyPEP study, conducted at two sexual health clinics in San Francisco and Seattle. It drew from a mix of transgender women and men who have sex with men, who had at least one diagnosed STI over the last year. The researchers divided the participants into two groups: one with people who were already HIV-positive and engaged in care, while the other group consisted of people who were on PrEP to prevent infection with HIV. For the active part of the study, a subset of the participants received doxy, and the rest of the participants did not.
The researchers intentionally chose to do the study in a population at the highest risk of having STIs, who were very health oriented, and “who were getting screened every three months or so as part of their PrEP program or their HIV care program,” says Connie Celum, a senior researcher at the University of Washington on the study.
Each member of the active group was given a supply of doxy and asked to take two pills within 72 hours of having sex where a condom was not used. The study was supposed to run for two years but, in May, it stopped halfway through, when a safety monitoring board looked at the data and recommended that it would be unethical to continue depriving the control group of the drug’s benefits.
Celum presented these preliminary results from the DoxyPEP study in July at the International AIDS Conference in Montreal. “We saw about a 56 percent reduction in gonorrhea, about 80 percent reduction in chlamydia and syphilis, so very significant reductions, and this is on a per quarter basis,” she told a later webinar.
In Kenya, another study is following a group of cisgender women who are taking the same two-pill regimen to prevent HIV, and the data from this research should become available in 2023. Senior researcher Victor Omollo, with the Kenya Medical Research Institute, noted that “these are prevention interventions that women can control on their own without having to seek or get consent from another person,” as is the case with condom use, another effective prevention tool.
Antibiotic resistance
Antibiotic resistance is a potentially big concern. About 25 percent of gonorrhea strains circulating in the U.S. are resistant to the tetracycline class of drugs, including doxy; rates are higher elsewhere. But resistance often is a matter of degree and can be overcome with a larger or longer dose of the drug, or perhaps with a switch to another drug or a two-drug combination.
Research has shown that an established bacterial infection is more difficult to treat because it is part of a biofilm, which can leave only a small portion or perhaps none of the cell surface exposed to a drug. But a new infection, even one where the bacteria is resistant to a drug, might still be vulnerable to that drug if it's used before the bacterial biofilm can be established. Preliminary data suggests that may be the case with doxyPEP and drug resistant gonorrhea; some but not all new drug resistant infections might be thwarted if they’re treated early enough.
“There are some tradeoffs” to these interventions, Celum says, and people may disagree on the cost of increased resistance balanced against the benefits of treating the STIs and reducing their spread within the community.
Resistance does not seem to be an issue yet for chlamydia and syphilis even though doxy has been a recommended treatment for decades, but a remaining question is whether broader use of doxy will directly worsen antibiotic resistance in gonorrhea, or promote it in other STIs. And how will it affect the gut microbiome?
In addition, Celum notes that we need to understand whether doxy will generate mutations in other bacteria that might contribute to drug resistance for gonorrhea, chlamydia or syphilis. The studies underway aim to provide data to answer these questions.
“There are some tradeoffs” to these interventions, Celum says, and people may disagree on the cost of increased resistance balanced against the benefits of treating the STIs and reducing their spread within the community. That might affect doctors' willingness to prescribe the drug.
Turning research into action
The CDC makes policy recommendations for prevention services such as taking doxy, requiring some and leaving others optional. Celum says the CDC will be reviewing information from her trial at a meeting in December, but probably will wait until that study is published before making recommendations, likely in 2023. The San Francisco Department of Public Health issued its own guidance on October 20th and anecdotally, some doctors around the country are beginning to issue prescriptions for doxy to select patients.
About half of new STIs occur in young people ages 15 to 24, a group that is least likely to regularly see a doctor. And sexual health remains a great taboo for many people who don't want such information on their health record for prying parents, employers or neighbors to find out.
“People will go out of their way and travel extensive distances just to avoid that,” says Mahn, the National Coalition director. “People identify locations where they feel safe, where they feel welcome, where they don't feel judged,” Mahn explains, such as community and family planning clinics. They understand those issues and have fees that vary depending on a person’s ability to pay.
Given that these clinics already are understaffed and underfunded, they will be hard pressed to expand services covering the labor intensive testing and monitoring of a doxyPEP regimen. Sexual health clinics don't even have a separate line item in the federal budget for health. That is something the National Association of STI Directors is pushing for in D.C.
DoxyPEP isn't a panacea, and it isn't for everyone. “We really want to try to reach that population who is most likely going to have an STI in the next year,” says Celum, “Because that's where you are going to have the biggest impact.”
