List of common misconceptions in the context of "Conventional wisdom"

The Cape of Good Hope (Afrikaans: Kaap die Goeie Hoop [ˌkɑːp di ˌχujə ˈɦuəp]) is a rocky headland on the Atlantic coast of the Cape Peninsula in South Africa.

A common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic and Indian oceans. In fact, the southernmost point of Africa is Cape Agulhas about 150 kilometres (90 mi) to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about 1.2 kilometres (0.75 mi) east of the Cape of Good Hope).

A misnomer is a name that is incorrectly or unsuitably applied. Misnomers often arise because something was named long before its correct nature was known, or because an earlier form of something has been replaced by a later form to which the name no longer suitably applies. A misnomer may also be a word that is used incorrectly or misleadingly. The word "misnomer" does not mean "misunderstanding" or "popular misconception", and a number of misnomers remain in common usage — which is to say that a word being a misnomer does not necessarily make usage of the word incorrect.

Totem poles (Haida: gyáaʼaang) are monumental carvings found in western Canada and the northwestern United States. They are a type of Indigenous Northwest Coast art, consisting of poles, posts or pillars, carved with symbols or figures. They are usually made from large trees, mostly western red cedar, by First Nations and Indigenous peoples of the Pacific Northwest Coast including northern Northwest Coast Haida, Tlingit, and Tsimshian communities in Southeast Alaska and British Columbia, Kwakwaka'wakw and Nuu-chah-nulth communities in southern British Columbia, and the Coast Salish communities in Washington and British Columbia.

The word totem derives from the Algonquian word odoodem [oˈtuːtɛm] meaning "(his) kinship group". The carvings may symbolize or commemorate ancestors, cultural beliefs that recount familiar legends, clan lineages, or notable events. The poles may also serve as functional architectural features, welcome signs for village visitors, mortuary vessels for the remains of deceased ancestors, or as a means to publicly ridicule someone. They may embody a historical narrative of significance to the people carving and installing the pole. Given the complexity and symbolic meanings of these various carvings, their placement and importance lies in the observer's knowledge and connection to the meanings of the figures and the culture in which they are embedded. Contrary to common misconception, they are not worshipped or the subject of spiritual practice, nor were they were used by all Indigenous peoples in the Americas.

Phototrophs (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light' and τροφή (trophḗ) 'nourishment') are organisms that carry out photon capture to acquire energy. They use the energy from light to carry out various cellular metabolic processes. It is a common misconception that phototrophs are obligatorily photosynthetic. Many, but not all, phototrophs photosynthesize: they anabolically convert carbon dioxide into biomolecules to be utilized structurally (e.g. cellulose and membrane lipids), functionally (e.g. vitamins, nucleotides, and amino acids), or as a source for later catabolic processes (e.g. starches, sugars and fats). All phototrophs either use electron transport chains or direct proton pumping to establish an electrochemical gradient, which is utilized by ATP synthase to provide adenosine triphosphate (ATP) for the cell. Phototrophs can be either autotrophs or heterotrophs. If their electron and hydrogen donors are inorganic compounds (e.g., Na
₂S
₂O
₃, as in some purple sulfur bacteria, or H
₂S, as in some green sulfur bacteria) they can be also called lithotrophs, and so, some photoautotrophs are also called photolithoautotrophs. Examples of phototroph organisms are Rhodobacter capsulatus, Chromatium, and Chlorobium.
