I asked six leading LLMs this question.Two of their answers surprised me. The rest were incorrect. Some were more misleadingly incorrect thanothers.This reveals a secret to designing effective and successful AI products. PerplexityYes, some mosquito species do bite leeches. A groundbreaking study by researchers at the University of Florida Institute of Food and Agricultural Sciences has revealed that the mosquito species Uranotaenia sapphirina feeds on the blood of earthworms and leeches. This discovery is significant because it challenges the long-held assumption that mosquitoes only feed on vertebrate animals.Key Findings Unique Feeding Behavior: Uranotaenia sapphirina, a common mosquito species in eastern North America, was found to obtain 100% of its blood meals from worms andleeches. Implications for Disease Transmission: This feeding behavior could potentially impact the transmission of pathogens. For example, Uranotaenia sapphirina mosquitoes that feed exclusively on worms and leeches have tested positive for Eastern equine encephalitis virus and West Nilevirus. Indirect Virus Contact: While the mosquitoes are unlikely to become infected with these viruses by feeding on worms, there is a possibility that they could come into contact with viruses by feeding on leeches that have previously fed on virus-infected animalhosts.Broader ImplicationsThis discovery expands our understanding of mosquito host ranges and feeding behaviors. It suggests that the potential hosts for mosquitoes are considerably broader than previously thought. This new information could have significant implications for our understanding of disease transmission and mosquitoecology.The study highlights the need for further research into mosquito-host interactions, particularly regarding invertebrate hosts. As Lawrence Reeves, the lead researcher, stated, This study really highlights that we still have much to learn about mosquitoes. Correctanswer. Provides links to sources and related information.

While its not the norm, some mosquitoes do indeed biteleeches.Heres what weknow:Mosquitoes have diverse diets: While many mosquito species prefer the blood of vertebrates like mammals and birds, some species have been found to feed on invertebrates.A specific example: Research has shown that the mosquito species Uranotaenia sapphirina specifically feeds on the blood of earthworms and leeches. This was a surprising discovery, as it was previously thought that these mosquitoes primarily fed on frogs andtoads.So, in short, while its not common for all mosquitoes, some species do bite leeches for their blood. This highlights the diverse feeding habits of mosquitoes and how much we are still learning about their behavior. Correctanswer. Provided two source links, but presented many facts that lacked citations. Didnt provide a way to share a link to the answer or the related conversation. Claude 3.5Sonnet:This is a fascinating but very obscure ecological question. Based on my understanding of mosquito feeding habits, they generally dont bite leeches. Mosquitoes typically feed on warm-blooded animals (mammals and birds) because they are attracted to body heat, carbon dioxide, and specific chemical signatures these animals produce. Leeches, being cold-blooded invertebrates, wouldnt produce these attractive signals.Additionally, leeches have a tough, muscular body wall that would likely be difficult for a mosquitos proboscis to penetrate, unlike the softer skin of their usualhosts.Since this is quite an obscure question about a very specific ecological interaction that may not be well documented, I should note that while I aim to provide accurate information, I may hallucinate when answering questions about such specific and uncommon interactions. If youre interested in this for research purposes, Id recommend consulting a parasitologist or checking scientific literature on mosquito host preferences. Wrong answer. But Claude prominently warned me that this specific answer may be wrong. This is a huge improvement over the other incorrect LLMs, which presented their wrong answers authoritatively.

ChatGPTo1There is no documented evidence or strong biological reason to suggest that mosquitoes feed onor biteleeches. Mosquitoes typically seek vertebrate hosts (such as mammals, birds, and sometimes reptiles) because they rely on cues like carbon dioxide, body heat, and certain body odors that are not produced in significant quantities byleeches.Why mosquitoes generally would not biteleechesHost detection:Mosquitoes use CO, heat, and chemical signals given off by vertebrates. Leeches (being invertebrates) do not emit these signals in a way that would attract mosquitoes.Feeding preferences:Mosquitoes are adapted to feed on vertebrate blood. While leeches do have a circulatory fluid, it is not the same as vertebrate blood, and it would not be considered a typical or efficient food source for mosquitoes.Habitat and behavior differences:Even though both mosquitoes and some leeches (particularly aquatic species) may share marshy or aquatic environments, their interactions are more or less incidental. Mosquitoes typically rest on surfaces above water or vegetation, while leeches remain in or very close to the water column or substrate, reducing any opportunity for directcontact.Consequently, while mosquitoes and leeches may coexist in similar habitats, mosquitoes do not typicallyand are not known totarget leeches as bloodmeal hosts.

Provides shareable link to the conversation: https://chatgpt.com/share/67730f81-98a0-8003-944b-1f4a1dc92cf5 MistralMosquitoes typically do not bite leeches. Mosquitoes are known to feed on the blood of various animals, including mammals, birds, reptiles, amphibians, and even some fish, but leeches are not a common target for them. Leeches themselves are blood-sucking creatures, but they feed on vertebrate animals, not on other invertebrates like mosquitoes.The feeding habits of mosquitoes and leeches are quite different, and there is no known ecological interaction where mosquitoes would feed on leeches. Mosquitoes use their proboscis to pierce the skin and suck blood, while leeches use their suckers and teeth to attach to their hosts and feed onblood. Wronganswer.

But even the best LLMs will hallucinate and get things wrong sometimes.Just as important as accuracy is helping people calibrate trust so they can make better decisions.Research shows a repeated pattern in human behavior around early AI tools: people tend to bounce between counterproductive extremes of overreliance and aversion:Initial overreliance: When encountering an AI tool, people frequently accept its suggestions without double-checking them. They trust it too muchmore than they would a humanexpert.Algorithm aversion: After the tool makes a mistake, people often shut down and reject even helpful AI assistance. They trust it too littleless than they would a human expert who made amistake.To succeed, designers need to keep people involved, to help them find a healthily skeptical middle ground. How? Were still hammering out the best practices, but here are three core guidelines:1. Surface sources, and link tothemPerplexitys approachlinking to primary research and showing its workhelped people verify its surprising claim.Without sources, even correct answers (like Geminis) are harder to trust andverify.Making sources easily checkable builds credibilityand more importantly it encourages people to get involved and verifyclaims.As fully Explainable AI (XAI) seems more and more an unrealistic pipe dream (though approaches to show me your train of thought show promise in certain contexts), source attribution is more important thanever.2. Highlight risk, and help people manageitClaudes answer was wrong. But Claude served it up in a way that made it less likely for people to repost it as truth. Other LLMs included easily-ignored, ever-present LLMs may sometimes hallucinate warnings off to the sidebut in the midst of an output that seemed at higher-than-usual risk of inaccuracy, Claude pointed out that higher risk and advised me to fact-check a specificclaim.This stands in stark contrast to ChatGPT, Mistral, and Llama, which confidently presented incorrect reasoningAcknowledging uncertainty helps prevent destructive overreliance on AI systems. Research shows that, when AI tools present calibrated uncertainty, users can adjust their reliance appropriately and reduce confirmation bias in their decisionmaking.3. Design for verification and collaborationAI tools should make it easy for people to shareand questionfindings with other humans. Chats should default to privacy, and sensitive conversations about personal information or trade secrets should be kept private. But for simple questions about public information, we can make it easier to share parts of any conversation with friends and colleagues, to reduce misunderstanding that comes from loss of context and to encourage further fact-checking. Features like shareable conversation links and integrated source citations should be standard, not afterthoughts.This isnt just good product design its essential for building collective knowledge and trust, and for defusing disinformation.The future of AI products wont be determined by their accuracy alone, but by how well they help humans make better decisions.By designing to the complementary strengths of humans and of AI, we can augment human intelligence and agency, rather than attempting to replacethem.Sources / more backgroundAlgorithm Aversion: People Erroneously Avoid Algorithms After Seeing ThemErrAI Overreliance Is a Problem.
