The iconography of culture in this day and age is easily accessible via image searches online where corporate logos, political seals and emblems, religious symbolism, and pop culture imagery can be accessed immediately. Using talismantic images an individual privately constructs in a public ritual space winds up falling somewhere in between these two ends of the iconographic spectrum. On the one end, there's the personal, and for all purposes asemic, sigils, and at the other end there's the nearly universal iconography of skulls for poison, lightning bolts for electrical voltage, and circles with slashes for "not allowed."
Whether working with sigilization, developing a personal alphabet for internal psychic work, or constructing memes for transmission into a larger social group, it helps to be conversant with the iconography and motivational triggers of that culture.
For examples of effective motivational triggers, consider these words and phrases: You. Proven. Guarantee. Make money. Save money. Save time. Look Better. Learn more. Money. Save. Results. Live longer. Feel comfortable. Discovery. Be loved. Love. Become popular. Experience pleasure. Health. Safety. Easy. New. These are only a small sampling of motivationally positive triggers60, and there's a whole host of negative triggers already established in our collective psyche too. Just listen in on any shortwave station or internet conspiracy theory podcast to get an idea of the vast array of negative psychological triggers out there. Political commercials during election campaigns also often rely on negative emotional triggers to influence voters' perceptions of political opponents, and nightly news segments often rely on similar techniques in their lead-ins to capture and hold the viewer's attention across commercial breaks.
